Amnesty International has condemned what appears to be the shooting dead of Syrian government soldiers by rebel fighters in a video posted online.

The human rights group said that the killings on Thursday - if confirmed - constituted a "war crime".

The BBC's Jim Muir says "the conflict is getting more vicious and more violent by the day".
