Iraq rocked by deadly blast in Tikrit Iraqi prime minister Nouri al-Maliki has faced months of protests in the country's Sunni heartland, which shares a border with Syria.

No group immediately claimed responsibility for the attack, but Sunni Muslim insurgents linked to al-Qaida have been increasing their efforts this year to undermine Iraq's Shia-led government and foment inter-communal conflict. The attack took place in central Tikrit, 150km (95 miles) north of Baghdad, 15 minutes after insurgents dhad driven the tanker inside a compound housing governmental administrative offices. It killed nine people, including seven police officers. Police at the scene said guards may not have suspected the tanker because fuel trucks arrive every morning to deliver gas and oil. The tank was stopped just behind the police administration building and partially damaged it. I was injured in my face and stomach because of glass," Captain Mohammed Salih said. Intensifying violence has accompanied the political crisis in Iraq, where a power-sharing government among Shia, Sunni and ethnic Kurdish blocks has been all but paralysed since US troops left more than a year ago. The prime minister, Nouri al-Maliki, a Shia, is also facing months of protests in the country's Sunni heartland, which shares a border with Syria. Many Iraqi Sunnis feel their minority sect has been sidelined by Maliki's government. Security experts say al-Qaida-linked militants have been regrouping in the western province of Anbar and crossing into Syria to fight alongside mainly Sunni rebels against forces loyal to President Bashar al-Assad, an ally of Shia Iran.
