Afghan suicide blast kills at least 5, wounds 16

Kabul, Afghanistan (CNN) -- A trio of blasts rocked the southern Afghanistan city of Kandahar Tuesday, killing at least 14 people and injuring 32, officials said.

On Tuesday evening, an improvised explosive device exploded without causing any injuries, said Zalmai Ayubi, spokesman for the Kandahar governor. But when police and locals gathered around the area of the blast, a suicide bomber on a motorcycle blew himself up near the crowd, he said.

Nine people -- including six police and three civilians -- were killed, according to Dr. Abdul Qayoom Pokhla, director of health department in Kandahar. Sixteen others were injured.

Earlier in the day, a suicide bomber on a motorbike targeted a police checkpoint, killing at least five people and wounding 16, the interior ministry said.

Among the dead were at least four children and a police officer, the ministry said.

No group immediately claimed responsibility for the attacks.
