A suicide bomber driving a truck loaded with TNT and toxic chlorine gas crashed into a police checkpoint in western Ramadi on Friday, killing at least 27 people and wounding dozens, police in the Anbar provincial capital said.

In the deep south of the country, the Basra police commander said the type of roadside bomb used in an attack that killed four British soldiers on Thursday had not been seen in the region previously. Maj. Gen. Mohammed al-Moussawi's description of the deadly weapon indicated it was a feared Iranian-designed explosively formed penetrator.

Two more of the bombs were discovered planted along routes heavily traveled by U.S. and British diplomats in Basra. Weeks earlier, the American military had claimed Iran was supplying Shiite militia fighters in Iraq with the powerful weapons, known as EFPs. They hurl a molten, fist-sized copper slug capable of piercing armored vehicles.
