U.S. suicide bomber loaded truck with explosives before blowing himself up in Syria

Shocking video shows the moment a 22-year-old American blew himself up in a suicide bombing last week in Syria. 

College drop out Moner Mohammad Abu-Salha, originally from Florida, is believed to be the first U.S. citizen to kill himself in a Syrian terrorist attack, the State Department said Friday.

The bombing was organized by an affiliate of al-Qaeda, and the group uploaded a video to YouTube of one of the four bombings that took place on May 25. 

In the video, men are seen loading a truck full of explosives, before driving off and detonating in a Syrian military compound.

Abu-Salha, who was named in postings to social media websites under the alias 'Abu Haraya Al-Amriki', reportedly arrived in Syria late last year, where he joined militants in the area.

Abu-Salha is believed to be involved with carrying out a rash of attacks in Syria's Idlib province. The attacks were carried out on behalf of Jabhat al-Nusra, an Al Qaeda affiliate attempting to oust the government of Syrian President Bashar Assad. 

Abu-Salha is believed to be the first American to commit a suicide bombing in Syria on behalf of Al Qaeda.
