From what I've read, the video below shows a Syrian soldier committing suicide to blow up the foreign-backed terrorists in an act of pure martyrdom for his country and his people. The terrorists were deceived into thinking he was one of them. I don't know if the soldier was kidnapped, or if he pretended to defect to the FSA and acted like one of them.
The video was uploaded by the members of the FSA, who lied by saying they were hit with an artillery strike, but after losing face, they pulled down the video. Luckily, the video made its way around by then.
The Syrian soldier is the one with the mic, singing at the beginning of the video.
Sorry for the poor explanation, but I'm a bit confused myself.
YouTube video description:
"The enemy still does not understand why they cannot break us.
Perhaps this video will show you why, even in the most desperate situation, we prefer victory over death and will never accept corruption of our values.
Our duty is one, to protect our land and our people.
NOTE: This video was uploaded by the FSA donkeys, pretending it was an artillery strike but quickly removed off the internet and now you know why."
