The Libyan Army say they have captured terrorists responsible for the deaths of the US Ambassador in the Benghazi attack in 2012 and a US teacher in 2013.

The Libyan National Army said they detained Islamists responsible for the deaths of Ambassador Christopher Stevens in 2012 and US chemistry teacher, Ronnie Smith, also murdered in Benghazi in 2013.

A spokesman for the Libyan National Army tweeted: 'Some of those involved in the attack on the U.S. consulate in #Benghazi and killed Ambassador #Stevens are in custody and will be prosecuted for this crime.'

Ambassador Stevens was murdered along with three other Americans by Islamic militants in an attack which shocked the world on September 11 2012.

He also said: 'In the case of the American teacher #RonnieSmith, assassinated in Benghazi in 2013, we announce that those who took part in this crime are in custody.'

They added that the chief who ordered the attack, Ahmed Bokhatala, was already in prison in the US.

There was no further information on the number of suspects or their identities.

Smith, from Texas, believed his Christian faith would guide and protect him when working in the volatile region.

The 33-year-old, who had a wife and young son, was brutally taken down while jogging in a drive-by with the killers riding in a Jeep in December 2013.

Smith's death came a year after the terrorist attack at the US consulate in Benghazi, as al-Qaeda's boss urged Libyans to attack Americans.

Ambassador Stevens was murdered along with three other Americans by Islamic militants in an attack which shocked the world on September 11 2012.

Former Secretary of State Hillary Clinton and has been heavily criticized by Donald Trump who feels diplomatic personnel were left completely exposed at the compound.

In 2016, the Republican members of the House Benghazi committee issued a blistering 800 page report which accused Clinton and President Obama of lying to the American people over what caused the attack.

It took more than 18 hours for a rescue mission to arrive at the Libyan city, but Clinton testified that they had done everything possible.

Trump went after Clinton for her use of a private email server which he believed covered the traces of her failing in 2012.

A month ago Trump told a rally in Montana: 'Thirty-three thousand e-mails. She gets a subpoena from the United States Congress.

'Forget about all the other things forget about it, and you can never forget about Benghazi,' he said. 'Never forget, Benghazi, but forget about all the other things.'

The Libyan National Army has sought to purge the country of Islamist militants after the country was torn apart by civil war after the death of Moammar Gadhafi in 2011.
