Islamic State conflict: Fighters seize Ramadi compound
Fighters from Islamic State militants have seized the main government building in Ramadi, the capital of Iraq's largest province.
As many as six suicide car bombs and mortars were used in the assault and at least 50 security personnel are reported to have been taken prisoner.
IS and Iraqi troops have been battling for months to take control of the strategically important Anbar province.
The BBC's Ahmed Maher says the offensive is a "massive setback" for the government.
