A rocket and mortar barrage followed by a car bomb blasted an upscale, mostly Shi'ite district Thursday, killing 31 people and wounding 153, police said.
The explosions occurred at midmorning in the religiously mixed neighborhood controlled by a major Shi'ite party, two days after President George W. Bush approved plans to send more US and Iraqi troops into the capital city to curb rising sectarian violence.
Several rockets and mortars landed in the district, some destroying a bank and an apartment building that later collapsed in flames, said Interior Ministry secretary Saadoun Abu al-Ula. The others exploded in the middle of busy streets crowded with traffic.
At least two rockets were used in the attack, said police Lt.-Col. Abbas Mohammed Salman in Karradah.
The car bomb exploded near a gas station, shattering storefronts and spraying flaming gasoline onto homes and stores, the Interior Ministry said. Charred hulks of trucks overturned on the streets. The front of an apartment complex was shorn away by the blast.
The explosion occurred about 200 meters way from the house of Vice President Adil Abdul-Mahdi, a Shi'ite and a senior figure in the Supreme Council of the Islamic Revolution in Iraq.
The mortars all landed in mainly commercial areas, with one exploding about 150 meters from SCIRI's headquarters in Karradah.
The attack was the largest on Karradah, a mixed neighborhood but mostly Shi'ite, in about a year. The area includes the home of President Jalal Talabani and the head of SCIRI, Abdul-Aziz al-Hakim.
Police Col. Abbas Mohammed Salman put the casualty toll as 31 dead and 153 wounded but said the deaths could rise because many of the injuries were severe.
Al-Maliki's office issued a statement condemning the attacks in Karradah, vowing to hunt down those who "attempt to incite sectarian strife."
Dozens of dazed, blood-soaked survivors shuffled through the rubble as emergency crews loaded weeping victims into ambulances, witnesses said.
The complex attack occurred as Iraqi Prime Minister Nouri al-Maliki was en route home from Washington, where he discussed the deteriorating security situation with President George W. Bush. The president agreed to send more US soldiers onto Baghdad streets to try to curb sectarian violence.
A steady rise in violence since Maliki's government took office May 20 has drawn new attention to sectarian militias and death squads, whose tit-for-tat killings have raised fears the country has begun to unravel.
Britain's ambassador to Iraq said Thursday that the security problem was made all the worse because Iraqis have lost confidence in the police.
Speaking on BBC Radio 4's Todayprogram, William Patey said evidence suggests some members of the police are linked to Shi'ite militias and Sunni insurgent groups.
"Undoubtedly the Iraqi people have lost confidence in the police," Patey said. "You move from optimism and pessimism. It's a fine dividing line."
Also Thursday, a car bomb exploded near a vegetable stand in Baqouba, 60 kilometers northeast of Baghdad, wounding three police said. Gunmen driving military vehicles and wearing uniforms hijacked two cars carrying money between banks, the Interior Ministry said.
Elsewhere, gunmen abducted three people walking near the al-Furqan Sunni mosque in north Baghdad around 4 p.m., police said. It was not clear who was taken or why they were grabbed.
During his address Wednesday to a joint session of Congress, Maliki insisted that his country is a front line in the war on terrorism and said those behind rampant violence are perverting the Islamic faith.
"Do not imagine that this problem is solely an Iraqi problem, because the terrorist front represents a threat to all free countries and free people of the world," Maliki said.
