BAGHDAD, Iraq — A barrage of coordinated bomb and rocket attacks on eastern Baghdad neighborhoods killed at least 47 people and wounded more than 200 within half an hour on Thursday, police and hospital officials said.

The latest spasm of violence — which included explosives planted in apartments, car bombs and several rocket and mortar attacks on mainly Shiite neighborhoods in the capital — came even as Prime Minister Nouri al-Maliki said Iraqi forces should have control over most of the country by year's end.

The Baghdad bombings — centered on neighborhoods controlled by Shiite militias, some of which Sunni Arabs accuse of running death squads — brought the day's death toll across the country to at least 68.

Attackers rented apartments and shops in buildings a few days ago and planted explosives in them, detonating them by remote control almost simultaneously Thursday evening, said Maj. Gen. Jihad Liaabi, director of the Interior Ministry's counterterrorism unit.

One of the targeted buildings was a medical center housing doctors' offices in al-Hamza Square on the outskirts of the Sadr City slum in east Baghdad, he told state television.

The attacks occurred between 6 p.m. and 6:30 p.m. and included a car bomb at a market, another behind a telephone exchange building and several rocket and mortar attacks, police said.

Police and witnesses said bodies had still not been recovered from the buildings and the death toll could rise.

The U.S. military also announced that two American soldiers and a Marine were killed Wednesday.
