BAGHDAD (Agencies) - Two suicide bombs tore through Baghdad on Sunday, killing 136 people, wounding more than 700 and leaving mangled bodies and cars on the streets in one of Iraqs deadliest days this year. The deadly bombings also sparked turmoil in the embattled Iraqi capital. The blasts shredded buildings and smoke billowed from the area near the Tigris River. The attacks occurred along a road thronged with traffic and destroyed three government buildings, the Ministry of Justice, the Ministry of Public Works and the Baghdad Governors Office, where ten members of parliament were attending a meeting. More than 700 people were also wounded in the mid-morning near-simultaneous attacks, the deadliest in Iraq in more than two years, an official said. The bombings, which the government said were carried out by Al-Qaeda and supporters of ex-dictator Saddam Husseins banned Baath Party, left streets littered with charred bodies and torn-off limbs, and buildings in ruins. They also destroyed dozens of cars and smashed water pipes, spewing dirty water into the streets. Authorities closed off roads leading to the bomb sites as fire trucks and ambulances struggled through thick traffic to reach the blazing buildings. One of the attackers exploded a truck bomb at a busy intersection near the justice and municipalities ministries, while the other detonated a car bomb opposite the nearby Baghdad provincial government offices. Shortly after the attacks, Prime Minister Nuri al-Maliki visited the site of the provincial government attack, where he spoke to officials and security officers. These cowardly terrorist attacks must not affect the determination of the Iraqi people to continue their struggle against the remnants of the dismantled regime and Al-Qaeda terrorists, who committed a brutal crime against civilians, Maliki said in a later statement. He said the attacks would not affect the political process or parliamentary elections due in January, and promised to punish those behind the bombings. Officials have blamed unnamed neighbours for not stopping the attacks - a reference to Iraqi complaints that Syria provides a safe haven for former Baathists while citizens of other Muslim states help fund the insurgency in Iraq. The neighbouring and distant countries should immediately refrain, forever, from harbouring, financing and facilitating forces that openly proclaim their hostility to the Iraqi state, President Jalal Talabani said in a statement. I dont know how Im still alive. The explosion destroyed everything. Nothing is still in its place, shop owner Hamid Saadi told Reuters by telephone from near the Justice Ministry. US forces provided forensics teams and bomb experts. Police sources said the bombs were carried in vans driven by suicide bombers while others said a truck and car were used. This breach is a big failure of the security forces who are responsible, along with the security officials, for what happened, said Jalal al-Din al-Sagheer, who heads the parliamentary bloc of the Supreme Islamic Iraqi Council, one of Malikis main rivals in the coming election. Haidar Assem, an employee of the ministry of municipalities, said he awoke to find himself in Al-Karama hospital, his head bandaged and his shirt covered in blood. Several people railed against the government and the security forces in the aftermath of the attacks, blaming them for the carnage. Where were the security forces? demanded Mohammed Radhi, who was searching for his sister, a justice ministry employee.
