Suicide bomber kills 37 in western Iraq - police officers, medical official

The blast killed 22 security personnel and 15 civilians, the medical and police sources said. The nine-storey building under construction, used as a base by security personnel, was located in the centre of Ramadi in western Anbar province.

Ramadi and its sister city Falluja have been plagued by fighting between the security forces and the extremist Islamic State and other armed groups since January.
