Sunni Arabs on a committee drafting Iraq's new constitution have ended a boycott after walking out last week to protest the assassination of two Sunni colleagues.
In announcing the return, panel member Saleh al-Mutlaq said demands for tighter security and an outside probe of the killings have been met. He said all 12 Sunni participants will rejoin the committee Tuesday.
The text of the constitution is due by August 15. But if the panel cannot complete the draft on time, it must act by August first to extend the deadline for six months.
Meanwhile, two suicide car bombings at police checkpoints in Baghdad killed at least eight people and wounded about 17 others on Monday.
Separately, the U.S. military says an American soldier was killed today when a roadside bomb exploded under his vehicle near Samarra.
