A female suicide bomber has killed at least eight members of a US-allied neighbourhood patrol in Iraq.
Police said the woman, wearing a traditional black robe, detonated an explosives belt in Baquba, capital of Diyala province, on Thursday night, leaving two dozen other people wounded.
Witnesses said Naaim al-Duliami, the local council chief, was killed together with seven of his bodyguards, a police officer speaking on condition of anonymity, quoted from a report on the bombing.
The attack comes as the US-backed Iraqi military prepares to expand operations in the province.
Earlier on Thursday, attackers killed three local council members in drive-by shootings targeting checkpoints in the Sunni neighbourhood of Azamiyah in northern Baghdad.
In the northern city of Kirkuk, the teenage son of a US-sponsored newspaper editor was killed by what police said might have been a sniper attack aimed at a passing US patrol.
And in Zafaraniyah, a predominantly Shia neighbourhood in Baghdad, Abdul-Rahman Dawood, a leading figure in the prime minister's Dawa party, was wounded in a bomb explosion near his house.
