Leaders of today's demonstration, estimated at around 1,000, also called for the release of Mustafa al-Yaqubi, a senior aide of al-Sadr. Spanish forces detained al-Yaqubi in Al-Najaf yesterday, accusing him of inciting violence.
There are also unconfirmed reports of violence at another pro-Sadr demonstration outside the holy city of Al-Najaf today.
Earlier today, the U.S. military said two U.S. Marines were killed yesterday in the western Anbar Province "as a result of enemy action." The province is where four American civilians were killed and their bodies mutilated by Iraqis on 31 March.
