At least six soldiers were killed Wednesday in Somalia's war-torn capital Mogadishu after suspected insurgents threw hand grenades, Radio Garowe reports.

The soldiers died in two separate explosions in Mogadishu's Yaaqshiid district, as they were passing through a key intersection at Towfiq.

"There were two explosions, only minutes apart," said a witness, adding: "Four soldiers died in the first explosion and two more died in the second [explosion]."

Witnesses told Mogadishu-based radio stations that at least four Somali government soldiers were wounded in the explosions, which was claimed by Al Shabaab insurgents.

Yesterday, one peacekeeper was killed and another wounded in a Mogadishu blast, the African Union Mission in Somalia (AMISOM) confirmed.

Mogadishu has been the scene of targeted explosions since Ethiopian troops invaded the country more than two years ago to assist the weak interim government.

The anti-Ethiopia insurgency has killed upwards of 10,000 people in a series of near-daily attacks, including shootouts, assassinations and roadside bombings.
