A gunman opened fire in a crowded US cinema killing two people and injuring several before turning the gun on himself Thursday, shortly after President Barack Obama deplored the nation's weak gun controls.
More than 100 people were in the theater when the man armed with a handgun began shooting indiscriminately into the audience about 30 minutes into a screening of "Trainwreck" at a cinema in Lafayette, Louisiana, police said.
Nine people were injured, some critically.
Police said they have identified Thursday's shooter as a 58-year-old white male, but did not release his name.
"We don't believe there's anybody else involved," Louisiana State Police Colonel Michael Edmonson told reporters.
President Barack Obama said earlier Thursday that a "instressing" lack of progress on gun control legislation has been a great source of frustration during his time in office.
"If you look at the number of Americans killed since 9/11 by terrorism, it's less than 100. If you look at the number that have been killed by gun violence, it's in the tens of thousands," Obama said in an interview with the BBC taped before the shooting.
"And for us not to be able to resolve that issue has been something that is distressing," he said.
The White House said the president was briefed late Thursday while en route to Kenya about America's latest mass shooting tragedy.
"The president directed his team to keep him updated on the investigation and on the status of those injured," White House spokesman Josh Earnest said in a statement.
"The thoughts and prayers of everyone at the White House, including the president and first lady, are with the community of Lafayette, Louisiana -- especially the families of those who were killed."
The violence came as a jury deliberates the death penalty for the gunman in a 2012 theater massacre in Colorado that left 12 dead and 70 injured.
Louisiana Governor Bobby Jindal rushed to Lafayette late Thursday, where he held a press conference not far from the shooting scene.
Jindal met with some of the victims at a local hospital and praised their "selfless heroism".
One teacher was badly wounded after throwing herself in front of a friend to shield her from the bullets. The friend was shot in the leg, but managed to "have the presence of mind" to pull a fire alarm in an effort to warn others of the danger, he said.
"Even in the worst of times, it brings out the best in people," Jindal told reporters.
Jindal, who is one of a crowded field of contenders vying for Republican presidential nomination, said it was not the right time to discuss gun control and that the focus should be on the victims.
The Louisiana shooting comes almost exactly three years after James Holmes, 27, opened fire on a packed screening of "The Dark Knight Rises" in Aurora, Colorado, in a meticulously-planned attack during which he wore body armor and used tear gas to prevent victims from escaping.
It also comes a week after Mohammad Youssuf Abdulazeez, 24, opened fire on two military centers in Chattanooga and killed four US Marines and a Navy sailor before dying in a shootout without police.
Authorities said the shooting victims range in age from the late teens to the 60s, and said police are still in the process of notifying their relatives.
Lafayette Police Chief Jim Craft said officers were able to respond within a minute of the first call for help.
"Four officers entered the theater to engage the shooter," he told reporters.
"They did hear shots being fired at the time. What they found upon making entry was it appeared the shooter died from a self-inflicted gunshot wound,"
Bodies remained in the theater while police conducted forensic analysis of the crime scene. That work was delayed, however, when a bomb squad was called in to examine the gunman's vehicle after a suspicious package was detected inside.
Television images from Lafayette showed a hectic scene at the cinema, surrounded late Thursday by dozens of emergency medical vehicles and police cars.
"It was crazy, chaos everywhere," witness Jacob Broussard told CNN.
Broussard was watching a movie across the hall when the sirens went off and the lights came on.
A voice came over the intercom asking people to evacuate the building as quickly as possible. As he was leaving, Broussard heard three shots. When he got outside, he saw a woman bleeding from the leg and realized something awful had happened.
Comedian Amy Schumer, who stars in "Trainwreck" swiftly offered her condolences.
"My heart is broken and all my thoughts and prayers are with everyone in Louisiana," she tweeted. (AFP)
