BAGHDAD: Australian Prime Minister Tony Abbott arrived in Baghdad on Sunday to discuss ways his country can boost Iraqi security forces in their fight against the IS group.

Abbott and his Iraqi counterpart, Haider Al-Abadi, discussed military cooperation between the two countries, including the training and equipping of Iraqi security forces, said Iraqi state television.

The Iraqi Army collapsed last summer in the face of a lightning IS group blitz that left about a third of Iraq and Syria in militant hands.

Australian fighter jets are launching airstrikes against IS group targets in northern Iraq as part of a US-led coalition and 200 Australian special forces troops will soon enter Iraq to advise and assist local security forces.

In Sunday’s violence, police said mortar shells slammed into several houses in the Shiite village of Sabaa Al-Bour, about 30 km north of Baghdad, killing four people and wounding seven.

Elsewhere, a bomb blast on a commercial street killed two people and wounded six others in western Baghdad.

Medical officials confirmed the casualties. All officials spoke on condition of anonymity because they were not authorized to speak to the media.
