A roadside bomb ripped off in northern Baghdad, the Iraqi capital, on Friday when a joint patrol of the Iraqi army and police were passing by, wounding 5 soldiers and 4 policemen, an Interior Ministry source said.

The blast happened near the Municipal Council of Baghdad in the district of Cairo on Friday noon and wounded nine members of the Iraqi security forces and one passer-by, the source told Xinhua on condition of anonymity because he is not authorized to speak to the media.

One army patrol vehicle and another police car were destroyed in the blast. Several buildings nearby were also damaged.

The police cordoned off the area and were searching for more possible explosive devices, the source added.

Iraq has seen a resurgence of violence in recent months. The Iraqi security forces and government officials in particular are targeted by insurgents.
