MOGADISHU, Jan. 16 (Xinhua) -- A convoy of Somali security forces was hit by a landmine in the outskirts of the capital Mogadishu Tuesday but there were no casualties reported so far.

A police officer who asked not to be named told Xinhua the convoy drove into the landmine in Mogadishu's Wardhigley district but said he could not confirm casualty figures.

"We have received reports of a landmine explosion targeting security forces in Wardhigley but we are yet to establish if there were any cases of injuries or deaths," the officer said.

Mustaf Muhidin, a trader in Harar-Yale area, said the blast was huge and caused scare in the area.

"I have visited the scene but I haven't seen any casualties. The blast was very huge and people had to scamper for safety."

The incident came barely three days after a similar attack caused injuries of Somali forces in Daynile district in Mogadishu.

No group has claimed responsibility but Al-Shabaab militants frequently carry out such attacks against the government and African Union bases in the Horn of Africa nation.
