Press TV reports.
The incident occurred in Mogadishu's northern district of Huriwa on Saturday when a land mine explosion hit a military vehicle.
No group has claimed responsibility for the incident.
However, a recent statement issued from Somalia’s al-Shabab fighters had promised to intensify their deadly attacks against the government and its foreign military supporters.
The Thursday statement also warned residents in government-controlled areas that more attacks will target those areas in the coming days or weeks.
“We reiterate our early warnings to the public to stay away from those areas under the control of the enemy. Those areas will be targeted in the campaign against the crusaders,” said al-Shabab spokesman Sheikh Ali Mohammud Dhere.
On Wednesday, the militant group carried out a deadly bomb attack in the capital, Mogadishu. A female bomber blew herself up inside Somalia’s National Theater as it was hosting an event marking the first anniversary of the Somali National Television.
Somalia has been the scene of a tug of war among armed groups and the Western-backed central government since warlords overthrew former dictator Mohamed Siad Barre in 1991.
At least 6 Somali troops have been killed and 10 others wounded in a heavy explosion in the north of the capital, Mogadishu,
