Iraq's political crisis shows no sign of easing a month after the Shi'ite-led government sought the arrest of a Sunni vice president, triggering fears that Iraq, without the buffer of U.S. troops, could return to sectarian conflict.
Accused of running death squads, Vice President Tareq al-Hashemi is holed up in Iraqi Kurdistan as a guest of Iraq's Kurdish president. The government of the semi-autonomous region has not responded to requests from Baghdad to hand him over.
The move against Hashemi, and Prime Minister Nuri al-Maliki's attempt to fire his Sunni deputy, Saleh al-Mutlaq, prompted a boycott of parliament and cabinet by the Sunni-backed Iraqiya bloc.
This has put stress on the fragile coalition of Shi'ite, Sunni and Kurdish parties forming Maliki's power-sharing government.
