The first explosion occurred in Ramadan neighborhood of Somalia capital as a convoy of Ethiopian and Somali government forces were passing. Two of Somali soldiers were killed and some nine others including Ethiopian soldiers and passers-by were wounded, Qaali Hassan, a resident in Ramadan neighborhood, told Xinhua.

Another blast in Huruwa District of Mogadishu claimed the lives of two civilians who were at the scene when a vehicle in an Ethiopian convoy was hit by explosion and soldiers opened fire.

Neither Somali nor Ethiopian officials, who usually do not speak to the media on casualties of attacks on them, were available to comment but residents in Ramadan neighborhood say the explosion was huge and soldiers sealed off the area and denied people access to it.

Residents also say that some people were also arrested in connection with the blasts.

The blasts come as a dusk to dawn curfew has been emplaced in the restive seaside city of Mogadishu for a week. The government says it aims to curb growing insurgency in the city which it blames on Islamists who are active in the capital. Explosions rock various parts of the capital at night time since the imposition of an indefinite curfew last Friday.

There has been an upsurge of violence since the Somali government announced the postponement of the national reconciliation conference until mid July.

Somalia has been without a central government since the overthrow of late ruler Mohamed Siyad Barre in 1991 when the country plunged into chaos until the formation of the current transitional federal government in Nairobi in 2004 as a result of the reconciliation conference there.
