Iraq militants promise more attacks on U.S. troops

An al Qaeda-linked militant group claimed responsibility for election day bombings in Iraq and vowed to continue attacks against U.S. forces, according to an audiotape. The group, the Islamic State of Iraq (ISI), had threatened voters before the March 7 parliamentary election. It called the election a farce aimed at cementing Shi'ite Muslims' domination of minority Sunnis. "We will continue to pursue the occupation, its helpers, and its agents, until we purify the land of their filth," said the audiotape posted late on Tuesday on a website used by jihadists. The site said the voice was that of ISI head Abu Omar al-Baghdadi. The speaker said the rocket, mortar and other attacks that killed 39 people on election day were aimed at keeping Sunnis from voting and not at killing them. Despite the threats 62 percent of Iraq's registered voters turned out to cast ballots.
