At least nine people have been killed and 31 wounded in a bomb attack on a security post in Iraq, police say.
The men, US-allied Sunni paramilitaries, or Sahwas, were killed in Iskandariya, 40km south of the Iraqi capital, while queuing to collect their wages on Saturday.
Muthana Khalid, an Iraqi police spokesman, said the bomber mingled into a crowd of about 250 people and blew himself up.
Ali al-Zahawi, the head of Iskandariya police, said: "The Sahwa men were preparing to enter the military post to receive their salaries when a suicide bomber managed to blow himself up among them, killing nine of them."
Relations strained
Relations between the Sahwas, also known as Awakening Councils, and the government in Baghdad led by Nuri al-Maliki have been strained in recent weeks by the arrest of Sahwa leaders.
There has also been tension over a delay in salaries being paid to the Sahwas in recent weeks, sparking concerns that the government could disband them.
"This was the third time we had come to get our salaries, because they postponed the payment the first two times," one Sahwa member wounded in Saturday's attack told the AFP news agency, asking not to be named.
The suicide attack came at the end of a particularly deadly week in Iraq, where a series of bombings killed 70 people and wounded more than 300.
In a truck bomb in the northern city of Mosul, five US soldiers and three Iraqi security forces were killed on Friday.
The Mosul bombing was the deadliest attack on American forces in more than a year and underscored the problem of maintaining security in some areas of the violence-wracked nation.
