BAGHDAD (AFP) - Attacks in Iraq killed nine people including three police on Tuesday, while militants bombed a major pipeline carrying oil to Turkey, halting exports, officials said.

The attacks are the latest in a surge in violence that security forces have failed to curb, despite carrying out major operations against militants said to have resulted in scores of arrests, including 82 on Monday.

In the deadliest attack on Tuesday, a car bomb exploded in the northern province of Kirkuk, killing three police.

Bombings also killed a soldier, a Sahwa anti-Al-Qaeda fighter and two civilians in Salaheddin province, north of the capital, while gunmen shot dead a former soldier and a civilian in the northern province of Nineveh.

And militants bombed a major pipeline carrying oil from northern Iraq to Turkey, near the town of Albu Jahash in Nineveh province.

The attack halted exports via the pipeline, a senior official from the North Oil Company said, adding that production was still continuing, but the oil was being stored.

Repairing the pipeline, which runs from the northern Iraqi oil hub of Kirkuk to the port of Ceyhan in Turkey, is expected to take between one and three days, the official said.

The attacks came a day after bombs targeting a cafe, a football field and a market in areas north of Baghdad killed 28 people.
