An explosion has killed at least 12 people and injured several others outside a court building in Pakistan’s capital Islamabad, police say.

“We are probing what kind of blast it was. It is not clear yet. We will be able to provide more details after we get a report from our forensic team,” a police spokesperson said on Tuesday. Aljazeera reported.

The blast occurred near the entrance of Islamabad district court, which is typically crowded with a large number of litigants.

Local media showed gory pictures of the site, with bloodied individuals lying near a police van.
