An Iraqi insurgent group has posted video on the internet which appears to show an attack on US troops in Iraq. It’s not clear if the footage is of a bomb blast which killed 10 marines near the former rebel city of Fallujah earlier this week – one of the deadliest attacks on US troops in recent months. The video was posted by a group calling itself the Islamic Army in Iraq, which has been linked to Saddam Hussein’s deposed Baath Party.In a statement, it also claimed to have killed and injured US troops in a battle on Saturday in a town north of Baghdad. Elsewhere, in Baquba north of the capital, insurgents attacked a patrol of soldiers, killing 19. Iraq is seeing an upsurge in violence ahead of parliamentary elections on December 15.
