Baghdad: A suicide truck bomber killed nine 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 latest attack, in Saddam Hussein's hometown of Tikrit, 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.

The attacker detonated the tanker truck at a police headquarters in Tikrit, 160 kilometres (100 miles) north of Baghdad, killing nine people and wounding 28, according to Mohammed Hassan Attiya, the head of the security committee within the provincial council of Salaheddin, of which Tikrit is the capital.

Among the victims were eight policemen who died and 25 who were wounded, Attiya said. Also north of the capital in the town of Tuz Khurmatu, gunmen wounded the mayor and his two bodyguards, officials said.

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

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."

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 a news agency 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 on a surprise visit to Baghdad last month.
