At least one person was injured when three mortar rounds rained down near Ethiopian embassy on Wednesday in the Somali capital, Mogadishu.
The shells landed into the capital’s heavily fortified zone, a witness said.
He says a civilian man was injured in the bombing.
It is unclear where the rockets were fired from.
No group says it has carried out Wednesday’s mortar attack, but such attacks are often carried out by Al Shabaab.
Mogadishu has seen frequently deadly explosions, with most of those attacks were claimed by Al Shabaab.
The group was pushed out of Mogadishu capital in 2011 by Somali army troops and 22,000-strong African Union force in Somalia.
The rebel group also lost most of their strongholds, but it still controls large rural areas and remains the key threat to peace in Somalia.
The group has been fighting for over ten years to overthrow the internationally-backed government in Somalia
