Bombing at Baghdad Recruiting Center

From Reuters:

A suicide bomber with explosives strapped to his body has attacked an Iraqi army recruitment centre in western Baghdad, killing 21 people and wounding more than 30.

The same bombing reported by Yahoo! News:

In the deadliest blast Sunday, a man strapped with explosives blew himself up at a west Baghdad airfield now used as a military recruiting center, police said. Early casualty reports varied, with a hospital official saying at least 16 died while a Defense Ministry employee reported up to 25 killed.

The explosion occurred just before 9 a.m. at the recruiting center, which had been hit several times before by suicide attackers. About 400 would-be recruits jammed the gate Sunday before the bomber detonated himself, police Sgt. Ali Hussein said.

There was another suicide attack on a police convoy in Mosul which killed four policemen and wounded three. Lastly, on a highway in Kirkuk, a Mercedes was used in a suicide bombing which specifically targeted civilians. Three were killed and 16 were wounded.

It's hard to stop people who are hell-bent on blowing themselves up.
