BAGHDAD (AP) — With political leaders deadlocked, Iraq’s parliament squabbled Monday over when to hold its next session, potentially delaying the formation of a new government for weeks despite the threat from extremists who have seized control of a large chunk of the country and declared the establishment of an Islamic state.

The acting speaker of parliament initially announced that the legislature would not meet again until mid-August because there was no agreement among factions over the top leadership posts — particularly the prime minister, with incumbent Nouri al-Maliki facing a campaign to replace him.
