Authorities in Iraq say continuing sectarian violence in Baghdad and other parts of the country has killed at least 16 more people.

Gunfire and bombs Thursday also wounded another 18 Iraqis.

Authorities say insurgents who detonated a bomb at a market in southern Baghdad killed at least four people and wounded 11 others.  Most of the victims were women.

A bomb that exploded in a bus traveling through a Shi'ite neighborhood of eastern Baghdad killed two people inside the vehicle and wounded four others on the street outside.

Gunmen also attacked the car of Adnan al-Dulaimi, a leader of the Sunni's largest parliamentary bloc, killing a bodyguard and wounding at least three others.

North of Baghdad, an attack on a security checkpoint killed at least six Iraqi soldiers and three policemen. 

Violent attacks across Iraq have killed hundreds of people since a bomb that exploded eight days ago wrecked the Askariya mosque, a revered Shi'ite Muslim shrine in Samarra. 

In other developments, Iraqi Prime Minister Ibrahim al-Jaafari canceled a meeting Thursday with the nation's top political leaders after they agreed to mount a campaign to deny him another term.

Sunni and Kurdish leaders say Mr. Jaafari is an obstacle to political unity.  On Wednesday, a spokesman for the influential Sunni Association of Muslim scholars denounced Baghdad's Shi'ite-led government for failing to prevent the past week's violence.
