There has been rise in the number of terror attacks in the northern Iraqi province of Kirkuk, prompting warnings from government officials that groups linked with al-Qaeda are making a comeback.

At least 16 people were killed in a suicide attack - seventh in the past six months - in the northern province this week.

Baghdad and Erbil squabble over control of Kirkuk, while security situation continues to worsen.
