Suicide truck bomb kills 11 as Iraq unrest spikes

Baghdad: A suicide truck bomber killed 11 people at a police headquarters on Monday as data showed March was Iraq's deadliest month since August, raising fears of a surge in violence leading up to elections.

The tanker truck was detonated at a police headquarters in Tikrit, slain dictator Saddam Hussein's hometown 160 kilometres (100 miles) north of Baghdad, also wounding 59 people, according to security and medical officials.

Among the victims were 10 policemen who died and 56 who were wounded, the sources said.

The attack comes as Iraq marks 10 years since the US-led invasion of the country that intended to oust Saddam and install a stable, democratic ally in the Middle East but instead unleashed brutal violence and endless political disputes.

Also north of the capital, separate attacks in Mosul, Tuz Khurmatu and near Tikrit left a policeman dead, a town mayor and his two bodyguards wounded, and a tribal chief kidnapped and his bodyguard wounded, officials said.

No group immediately claimed responsibility for the Tikrit attack, but Al-Qaeda-linked Sunni militants often use suicide bombers and explosives-laden vehicles to target security forces and officials in a bid to destabilise Iraq.

The bombing comes ahead of provincial elections scheduled for April 20, due to be held in 12 of Iraq's 18 provinces, the country's first polls since a parliamentary vote in March 2010.

"Because we are approaching elections, which are a key event in the country, this is pushing terrorist groups... to carry out maximum damage against internal security," a senior security official told AFP, speaking on condition of anonymity.

"They are aiming to hinder the elections."

John Drake, a London-based security analyst for AKE Group, warned insurgent groups may be trying to "instil the electorate into voting along sectarian lines, further dividing society, which in turn harms the government's efforts to consolidate voters."

"A divided society is also easier for the terrorists to operate in."

Questions have been raised about the credibility of the polls as they have been postponed in two provinces roiled by months of protests, and 11 candidates have been killed, according to an AFP tally.

Officials cited security threats to candidates and election officials in justifying the delay in Anbar and Nineveh province, but diplomats have voiced concern over the move.

"The fact is that while security has been put forward as a rationale for that postponement, no country knows more about voting under difficult circumstances than Iraq," US Secretary of State John Kerry said in Baghdad last month.

The vote is seen as a key barometer of support for Prime Minister Nuri al-Maliki as he grapples with criticism from within his unity cabinet and protests in the minority Sunni Arab community.

Though violence remains high by international standards, Iraq's military and police are consistently described by Iraqi and American officials as capable of maintaining internal security, but are not yet fully able to protect the country's borders, airspace and maritime territory.

Figures compiled by AFP and based on reports from security and medical officials, meanwhile, showed March was the deadliest month in Iraq since August with 271 people killed and 906 wounded in attacks.

The death toll was sharply higher than the toll for February, when 220 people were killed and 571 were wounded.

Iraq has largely eschewed any formal ceremonies marking the date of the invasion, but events are likely to be held on April 9, which marks the day Baghdad fell and is typically reserved as a public holiday.
