MAN SHOT TO DEATH WHILE QUESTIONED IN BOSTON PROBE
 
ORLANDO, Fla. (AP) -- A Chechen immigrant was shot to death by authorities while being questioned in the Boston Marathon bombing investigation early Wednesday after he lunged at an FBI agent with a knife, officials said.
 
Ibragim Todashev, a 27-year-old mixed martial arts fighter, was gunned down at his Orlando home during a meeting with the agent and two Massachusetts state troopers, authorities said. The agent was taken to a hospital with injuries that were not life-threatening.
 
The FBI gave no details on why they were interested in Todashev. But acquaintances said Todashev knew one of the Boston Marathon bombing suspects, Tamerlan Tsarnaev, from mixed martial arts fighting in Boston. Public records also show Todashev lived in Watertown, Mass., just outside Boston, last year.
 
Tamerlan Tsarnaev, an aspiring boxer, was killed in a shootout with police days after the April 15 bombings. His brother, Dzhokhar, survived and is charged with carrying out the attack that killed three people and wounded more than 260.
 
Muslin Chapkhanov, a former roommate of Todashev's in the Orlando suburb of Kissimmee, said Todashev knew the older Tsarnaev brother. "He was living in Boston and I think he trained with him," Chapkhanov told The Associated Press.
 
CAMERON: 'INDICATIONS' LONDON ATTACK TERROR
 
LONDON (AP) -- A brazen, brutal attack near a military barracks in London on Wednesday afternoon left one man dead and two suspects in the hospital. British Prime Minister David Cameron said the attack appeared to be terror-related.
 
The attack occurred in the southeast London neighborhood of Woolwich, just a few blocks from the Royal Artillery Barracks.
 
Two men reportedly attacked another man. Witnesses said the two men were shot by police and a number of weapons - including butchers' knives - could be seen on the street, which was splattered by blood.
 
French President Francois Hollande, speaking at a press conference in Paris with Cameron, said it was a British soldier who was killed. Cameron didn't immediately confirm that fact but the Britain's Ministry of Defense said it was urgently investigating the attack.
 
Cameron did say said there were "strong indications" it was a terrorist incident.
 
POLISH MAN GETS QUICK FACE TRANSPLANT AFTER INJURY
 
WARSAW, Poland (AP) -- A 33-year-old Polish man received a face transplant just three weeks after being disfigured in a workplace accident, in what his doctors said Wednesday is the fastest time frame to date for such an operation. It was Poland's first face transplant.
 
Face transplants are extraordinarily complicated and relatively rare procedures that usually require extensive preparation, typically months or years. But medical officials said the Polish patient's condition was deteriorating so rapidly that a transplant was seen as the only option. The patient is now being watched for any potential infections.
 
The patient worked at stonemason's workshop near the southwestern city of Wroclaw where on April 23 a machine used to cut stone tore off most of his face and crushed his upper jaw.
 
"We assume the surgery will allow the patient to return to normal life. He will be able to breathe, to eat, to see."
 
The patient is now breathing on his own and responds to questions by nodding his head or squeezing the hands of doctors. But his condition is serious and it will be months before the doctors can describe the procedure as a full success, said Dr. Krzysztof Olejnik, head of the team of anesthesiologists.
 
Another member of the transplant team, surgeon Dr. Michal Grajek, told The Associated Press that the patient is receiving drugs to ward off any potential viral, bacterial or skin infections.

THE 50TH SUPER BOWL GOES TO SAN FRANCISCO BAY AREA
 
BOSTON (AP) -- The 50th Super Bowl will be held in the San Francisco Bay Area.
 
NFL owners have voted Tuesday for the 49ers' new stadium as host of the 2016 game. That facility in Santa Clara, Calif., is due to open for the 2014 season.
 
San Francisco beat out South Florida, which was stymied in its bid to stage an 11th Super Bowl when the Florida Legislature did not support financing to renovate Sun Life Stadium.
 
The 2017 Super Bowl will be held in Houston, which also beat out Miami for that game.
 
The only previous Super Bowl played in northern California was at Stanford Stadium in 1985.
 
Houston hosted the 2004 NFL championship game.
 
Earlier Tuesday, owners approved a $200 million loan for stadium construction in Atlanta.
 
MORE TORNADOES FROM GLOBAL WARMING? NOBODY KNOWS
 
A deadly tornado hit suburban Oklahoma City on Monday. A quick look at some basic facts:
 
Q. Is global warming to blame?
 
A. You can't blame a single weather event on global warming. In any case, scientists just don't know whether there will be more or fewer twisters as global warming increases. Tornadoes arise from very local conditions, and so they're not as influenced by climate change as much as larger weather systems like hurricanes and nor'easters. They're not easy to incorporate in the large computer simulations scientists use to gauge the impact of global warming.
 
And when scientists ponder the key weather ingredients that lead to twisters, there's still no clear answer about whether to expect more or fewer twisters. Some scientists theorize that the jet stream is changing because sea ice in the Arctic is shrinking. And the jet stream pattern drives weather in the Northern Hemisphere.
 
Q. How does this tornado season stack up against previous ones?
 
A. The season got off to a quiet start this year. Typically, there are more during spring, and the numbers dwindle in the worst heat of the summer. An unusually cool spring kept the funnel clouds at bay until mid-May this year. The last two seasons illustrate the extremes in tornado activity. In 2011, the United States saw its second-deadliest tornado season. Last year, it was busy in April but there were few twisters after that.
 
Q. What happened in Oklahoma?
 
A. The tornado destroyed an elementary school and flattened neighborhoods with winds up to 200 miles an hour. The National Weather Service made a preliminary ranking of the twister as an EF4, the second-most-powerful classification.
 
Q. How did it form?
 
A. Like the most destructive and deadly tornadoes, this one came from a rotating thunderstorm. The thunderstorm developed in an area where warm moist air rose into cooler air. Winds in the area caused the storm to rotate, and that rotation promoted the development of a tornado.
 
MICROSOFT TOUTS XBOX ONE AS ALL-IN-1 ENTERTAINMENT
 
REDMOND, Wash. (AP) -- Microsoft thinks it has the one.
 
The company unveiled the Xbox One, a next-generation entertainment console that promises to be the one system households will need for games, television, movies and other entertainment. It will go on sale later this year.
 
Don Mattrick, Microsoft's president of interactive entertainment business, said the company has spent the past four years working on the "all-in-one home entertainment system."
 
The console was demonstrated Tuesday at Microsoft's Redmond, Wash., headquarters using voice control to seamlessly switch back and forth between watching live TV, listening to music, watching a movie, browsing the Internet, as well as simultaneously running apps.
 
Microsoft executives touted the Xbox One as a replacement for the set-top box from your cable provider. It has its own guide and you can change channels by voice command.
 
Microsoft also unveiled a new version of its camera-based Kinect system with better motion and voice detection. It showed how users can watch live sports on TV while getting updates on fantasy leagues on a split screen. In an effort to stay ahead of rivals, Microsoft said new content for the popular "Call of Duty" game can be downloaded on the Xbox One before any other system.
 
Microsoft says more games will be shown at next month's E3 video game conference in Los Angeles.

MASSIVE TORNADO ROARS THROUGH OKLAHOMA CITY SUBURB
 
MOORE, Okla. (AP) -- A monstrous tornado as much as a mile wide roared through the Oklahoma City suburbs Monday, flattening entire neighborhoods, setting buildings on fire and landing a direct blow on an elementary school.
 
There were no immediate reports of injuries or deaths, but the storm laid waste to scores of buildings in Moore, south of the city. Block after block of the community lay in ruins, with heaps of debris piled up where homes used to be. Cars and trucks were left crumpled on the roadside.
 
Volunteers and first responders were searching through debris looking for survivors. Television footage showed first-responders picking through rubble and twisted metal.
 
Oklahoma City Police Capt. Dexter Nelson said downed power lines and open gas lines posed a risk in the aftermath of the system.
 
The storm seemed to blow neighborhoods apart instantly, scattering shards of wood and pieces of insulation across the scarred landscape.
 
The same suburb was hit hard by a tornado in 1999. That storm had the highest winds ever recorded near the earth's surface.
 
MORE OBAMA AIDES KNEW OF IRS AUDIT; OBAMA NOT TOLD
 
WASHINGTON (AP) -- White House chief of staff Denis McDonough and other senior advisers knew in late April that an impending report was likely to say the IRS had inappropriately targeted conservative groups, President Barack Obama's spokesman disclosed Monday, expanding the circle of top officials who knew of the audit beyond those named earlier.
 
But McDonough and the other advisers did not tell Obama, leaving him to learn about the politically perilous results of the internal investigation from news reports nearly three weeks later, officials said.
 
The decision to keep the president in the dark underscores the White House's cautious legal approach to controversies, as well as an apparent desire by top advisers to distance Obama from troubles threatening his administration.
 
Obama spokesman Jay Carney defended the decision to keep the president out of the loop on the Internal Revenue Service audit, saying Obama was comfortable with the fact that "some matters are not appropriate to convey to him, and this is one of them."
 
"It is absolutely a cardinal rule as we see it that we do not intervene in ongoing investigations," Carney said.
 
Republicans, however, are accusing the president of being unaware of important happenings in the government he oversees
