At least seven people, including two children, have been killed in separate explosions in Mogadishu, the latest attacks in fighting between Islamic militants and government troops in Somalia.
The two children were killed in a blast Friday in the south of the Somali capital, near a United Nations compound.

At least five other people were killed in separate explosions today throughout the city.

Hours earlier, security officials displayed a large cache of weapons seized in house-to-house searches throughout Mogadishu.

Violence in the Horn of Africa nation is worsening following a third postponement of a national reconciliation peace conference on Wednesday. 

Earlier, an explosion at a public screening of a foreign film killed at least four people and wounded at least six others in southern Somalia.

A crowd of more than 100 had gathered late Thursday to watch an Indian film at a movie theater in Baidoa, a city about 250 kilometers from Mogadishu.

Local officials believe the explosion may have been caused by a hand grenade but are still investigating.

Somalia has not had an effective central government since the overthrow of dictator Mohamed Siad Barre in 1991.
