MOGADISHU, Somalia

At least four people were killed and several others wounded in bomb blasts in southern Somalia on Tuesday, officials said.

The explosions took place in the vicinity of Buula-haji near Somalia’s port city of Kismayo, the administrative capital of southern Jubaland state.

At least 11 people – all civilians – were also wounded, a security official in Kismayo told Anadolu Agency on a condition of anonymity due restrictions on speaking to the media.

The Somali state television reported that nine landmine explosions targeted a minibus carrying civilians.

Kismayo is a major city and port town, located 500 kilometers (310 miles) south of Mogadishu, Somalia's capital.

No group has yet claimed responsibility for the deadly bomb attacks, but authorities blamed al-Shabaab, a terrorist group affiliated with al-Qaeda, for the blasts.
