A suicide bomber detonated explosives outside a district court in Pakistan's capital, Islamabad, on Tuesday, killing at least 12 people and injuring dozens.
The attack occurred during one of the court's busiest hours, with the interior minister stating the bomber targeted a police vehicle after failing to enter the court premises.
At least 27 people were reportedly wounded in the blast, which was powerful enough to be heard miles away and caused significant damage.
No group has yet claimed responsibility for the bombing, which is part of a renewed wave of militant violence in Pakistan.
Separately, Pakistani security forces thwarted an attempted attack on an army-run cadet college near the Afghan border and reported other militant incidents, including an IED attack and operations killing 20 Taliban militants.
