Iraq's biggest tribe has appealed for weapons to defend itself against the Islamic State jihadist group after several of its members were abducted and killed in a central desert region.
The Shammar are a particular target for IS because they sided with the government in the battle with the jihadists, who were expelled from their last urban strongholds last year.
"We hold the security forces responsible for protecting civilians... failure to do so is a failure of duty," Shammar leader Sheikh Abdallah Hmeidi Ajeel al-Yawar said in a statement on Tuesday.
"If the security forces are unable to control these areas inhabited by the Shammar and other tribes... the commander-in-chief (of the armed forces Prime Minister Haider Abadi) should open the door for volunteers to join the ranks of the army and form a brigade of sons of the region to protect themselves."
