There's one less player now on the chaotic streets of Basra, where the Iraqi government and contending parties and gangs are scrapping for control of Iraq's oil-rich second city. Reports have emerged in the last couple of days that government forces have detained Yussef al-Mussawi, leader of a shadowy fundamentalist group, Thar-Allah–"God's Revenge." Newsweek wrote about Mussawi last October, describing how local warlords exert more authority than the central government. He worked from a compound on the edge of the city, surrounded by his heavily armed aides.

Government officials say he is behind a string of assassinations, including the killings of professionals and women, the latter apparently because they were not maintaining strict codes for modest dress and behavior. They also accuse Mussawi of ties to Iran's Revolutionary Guard Corps. But some see the recent wave of arrests as an attempt by leading government Shiite parties to neutralize Shiite rivals.
