PRESIDENT DONALD TRUMP has approved the execution by firing squad of Nidal Hasan, a US Army psychiatrist who shot dead 13 people at a military base in 2009, according to the Pentagon.

Hasan’s execution for the attack at Fort Hood in Texas – which also wounded more than two dozen people – will be the first carried out by the US military since 1961.

Christa Pike – a Tennessee inmate who last week survived two attempts to execute her using lethal injection – had asked to be shot by an all-female firing squad ahead of her execution. 

Pike’s legal team had previously objected to the execution’s IV protocol, saying it would have caused needless suffering due to her small veins and a blood condition.

A Pentagon spokesperson said Defence Secretary Pete Hegseth recommended death by US Army firing squad for Hasan.

“The Secretary of the Army will set the time and place of the execution. Judgement day for Hasan has finally come,” spokesperson Sean Parnell wrote on X.

Hasan was sentenced to death by a military jury in 2013 for carrying out the Al-Qaeda inspired mass shooting at Fort Hood.

He chose to conduct his own defence during the trial but called no witnesses and gave no testimony, and made no attempt to deny the charges. Court-appointed defence attorneys expressed concern that he was seeking execution.

Hasan, a US-born Muslim of Palestinian descent, opened fire on 5 November 2009, at a medical facility in the sprawling Fort Hood base, which served as a staging point for soldiers to deploy to combat zones in Iraq and Afghanistan.

Twelve of the dead and 30 of the wounded were soldiers. Hasan was shot and partially paralysed by a civilian police officer who responded to the attack.

The court that convicted Hasan was told that he was opposed to the US military’s occupations of Iraq and Afghanistan, and that he had spoken online with an alleged Al-Qaeda figure, radical cleric Anwar al-Awlaki, an American citizen subsequently killed in a US drone strike in Yemen.

While mass shootings in the United States are common, they are rare at military facilities.

In 2025, a soldier opened fire at a US military base in the state of Georgia, wounding five fellow troops before he was tackled and apprehended.

In 2019, a US sailor fatally shot two people and wounded a third at a base in Hawaii, while a Saudi military student shot dead three people at a military facility in Florida the same year.

A Kuwaiti-born US citizen attacked two military installations in Tennessee in 2015, killing four Marines and a sailor. The FBI concluded the violence was inspired by a “foreign terrorist group.”

Two years earlier, a man killed 12 people and wounded eight at the Washington Navy Yard in the US capital, before being shot dead by officers.
