BBC News reports: Iraqi MPs have approved new defence and interior ministers, completing a unity government that is battling the spread of Islamic State militants.

Mohammed Salem al-Ghabban, a Shia, was appointed interior minister, while Khaled al-Obeidi, a Sunni, was confirmed as defence minister.

IS controls large parts of the country, and has been making gains despite US-led coalition air strikes.

On Friday, a curfew was imposed in the city of Ramadi amid fierce fighting.

The vote by Iraqi MPs will be a big relief both inside and outside Iraq after weeks of wrangling, says BBC Arab affairs editor Sebastian Usher.
