Two people were killed and five others were injured in an explosion in Bosaso town in northeast Somalia Saturday, just hours after an attack in the central town of Beledweyne killed 13 people and wounded 18 others, police said.

"Two people were killed and five others wounded in a terrorist bomb attack targeting a tea shop in Bosaso town of Puntland state," state-owned Radio Mogadishu reported.

The police said the latest blast targeted electoral delegates who participated in the ongoing lower house elections Friday.

Local media reported earlier at least 13 people have been killed and 18 others injured after a suicide bombing at a busy restaurant in Beledweyne, capital of the Hiran region in Somalia.

According to Radio Mogadishu, Abdirahman Keynan, the deputy district commissioner for social affairs, is among those killed in the Beledweyne bombing.

There was no immediate claim of responsibility for the attack in Bosaso, but al-Qaida-linked al-Shabab insurgents have carried out a string of similar bombings in the past in Mogadishu, the capital of Somalia, and elsewhere in the country.

The militant group claimed responsibility for the suicide attack in Beledweyne, which has been condemned by Prime Minister Mohamed Roble.
