Two people were killed and several injured after gunmen stormed Turkish centre in the Somali capital Mogadishu on Saturday, witnesses and police said.

The Turkish centre is used by staff of Turkish's Red Crescent and Embassy staff in Mogadishu.

"Two people including a guard died and several others were wounded in attack on the Turkish centre," police officer Ali Yare told Xinhua.

Reports indicate that Turkish nationals may be included in the casualties.

The attack is the second in few hours in Mogadishu after bomb planted inside a government vehicle went off at a junction in the north of the city.

Somali government has strongly condemned the attack which comes as the rebel group of Al Shabaab vowed to increase their attacks during the Holy month of Ramadan.

"I condemn in the strongest possible terms, the bomb explosion that have taken place today near the Turkish Embassy in Mogadishu, " tweeted the Somali Foreign Minister, Fawzia Yusuf Adam.

Al Qaida-linked Al Shabaab has claimed responsibility for the attacks on the Turkish centre in Mogadishu.

"Mujahideen forces in Mogadishu have just carried out an operation targeting a group of Turkish diplomats in Hodan district, " the militant group said on its twitter feed.

The radical group accused Turkey of supporting Somali government and of opposing the establishment of Sharia law in Somalia

The Al Shabaab has carried out similar assaults against targets of Somali government and its allies including African Union peacekeeping forces in the horn of Africa country.

Turkey is one of the few countries that have reopened their embassies in war-ravaged Mogadishu.

Al Shabaab group have previously condemned Turkish involvement in Somalia and this marks the first direct attack against Turkey installation in the capital.
