Iraqi legislators finished their session Thursday without agreeing on an election law needed to carry out the country's January vote.

The death toll from Iraq's biggest attack in more than two years grew to 155 Monday as Iraqis buried the victims from the twin suicide bombings that took place at the heart of Baghdad.

Two huge car bombs went off in downtown Baghdad Sunday, killing at least 136 people in an attempt to target the city's government offices, Iraqi medical officials and authorities said.
