The gunman who opened fire at a Sikh place of worship in the United States, killing six people, died of a self-inflicted gunshot wound to the head, the FBI has announced.
It happened after a police officer shot and wounded Wade Michael Page in the stomach outside the temple in Oak Creek, Wisconsin, Special Agent Teresa Carlson, head of the FBI's Milwaukee field office, told a news conference.
"Subsequent to that wound, it appears that Page died from a self-inflicted gunshot wound to the head," she said.
The agent said she had seen a video of the police officer wounding Page with a squad rifle. "It's an amazing shot, and thank goodness," she said.
Authorities had previously said an officer responding to the August 5 attack had fired the shot that killed Page, who was armed with a 9mm handgun.
Investigators have not yet found a motive for the attack, which also wounded four people, including a police officer, Lieutenant Brian Murphy.
Page, a psychological operations specialist in the US Army between 1992 and 1998, was a musician who played in white power punk-metal bands.
Police are investigating the 40-year-old's links to white supremacist groups and have said they are treating the attack - which left five men and a woman dead - as a possible act of domestic terrorism.
President Barack Obama called Indian Prime Minister Manmohan Singh on Wednesday to express his condolences over the incident.
Mr Singh is India's first prime minister from the Sikh faith, and several victims of the shooting were from India.
White House press secretary Jay Carney said the two leaders discussed their "shared commitment to tolerance and religious freedom".
Police are interviewing dozens of people who knew Page to determine a possible motive for the killings.
"We just want to get to the bottom of what motivated him to do it," said Amardeep Singh, an executive with the New York-based Sikh Coalition.
"It's important to acknowledge why they lost their lives."
Page's former girlfriend, Misty Cook, was arrested by police at her Milwaukee home on Sunday on a weapons charge. The arrest was unrelated to the shootings probe.
