An Iraqi judge was killed Friday when militants attacked him on his way to his house in eastern Baghdad, reported dpa.
Sources told Deutsche Presse-Agentur dpa that militants shot dead Kamal al-Showeily in Baghdad's Qana district.
In other news, at least 20 people - including three US marines and two interpreters - were killed in an attack that targeted a meeting of clan chiefs and tribal leaders in the town of Karma in the western province of Anbar on Thursday, a US military statement said.
The attacker managed to enter through an unguarded gate, al-Arabiya news channel said. Senior local officials and clan chiefs were reported to be among those killed.
The US deaths pushed the number of that country's troops killed since June to 29, while 4,113 US personnel have been killed since the US-led invasion of Iraq in 2003.
The US military will delay the handover of security responsibilities in Anbar province due to the attack and other conditions, al-Iraqiya state television said on Thursday.
The province is scheduled to become the first Sunni province to be transferred to Iraqi security control on Saturday.
It will be the 10th of Iraq's 18 provinces to revert to Iraqi control. The previous nine have been Kurdish or Shiite.
