Executing the wounded in Fallujah

I've just been emailed by a friend in the UK, who informs me that just a few minutes ago, BBC was showing

film and sound of US Marines shooting, i.e: executing wounded Iraquis who had already surrendered. And they did it in a Mosque.

BBC reporters are saying this is "worse than Abu Grahib" and their primary anchorman is saying the words "war crimes".

The BBC story is here:

The images were taken by an NBC reporter embedded with the US troops in the Sunni city under assault.

[...]

[They] show a group of marines, armed with rifles, entering a building near a mosque.

The mosque had been used by insurgents to attack US forces, who had stormed it, killing 10 militants and wounding five.

At least three severely wounded men are seen in a room inside the building - two are slumped against one of the walls, partially covered with a blanket.

The NBC's Kevin Sites says the wounded men had been left in the mosque after marines had fought their way in on Friday and Saturday.

According to Mr Sites, one of the soldiers points his rifle at the head of one of the injured, an old man. The sound of a shot is then heard.

The Marine has been arrested, and may face charges, but his actions have endangered the lives of every single US soldier. The Geneva Conventions and their rules for the treatment of the captured and wounded exist for good reason, as John McCain can testify. But if the US treats injured Iraqis like this, they can expect no mercy whatsoever if they are ever in a similar situation.

Update: More from Yahoo. I'd add that this is exactly the sort of thing you'd expect when your president and his White House Counsel (soon to be Attorney-General) don't believe in the Geneva Conventions.
