At least six people have been killed and several others injured in a powerful explosion outside a courthouse in Islamabad, Pakistani police say.
The blast occurred while a large number of people were gathered at the judicial complex, though the cause and those responsible remain unclear.
Security forces have sealed off the area, and a thorough investigation is underway to identify the perpetrators.
Officials confirmed that the injured have been taken to local hospitals, with some in critical condition.
No organization has claimed responsibility for the attack, and police have urged the public to remain vigilant as the investigation continues.
