Nine people have been killed and at least 20 others injured in a blast in Pakistan's northwestern city of Peshawar.
The bomb went off as a school bus passed alongside a car parked in the busy Kashkal area of the city.
Local police official Abdul Gahfoor said it was a car bomb, which damaged more than a dozen vehicles and a nearby internet cafe.
Earlier, a suspected US drone aircraft fired missiles at militants in the North Waziristan ethnic Pashtun tribal region, to the southwest of Peshawar, killing ten people.
One missile hit a house in the Khaisor area of North Waziristan's ethnic Pashtun tribal region. Another struck a nearby vehicle.
Khaisor is about 20km south of Mir Ali town, a hub for foreign militants in the region.
Pakistan's military has said that 47 militants were killed over the last 24 hours in its air and ground offensive against the Taliban in three northwestern districts.
It was third such attack this month. This week, eight people were killed in a similar attack in neighbouring South Waziristan.
The US, alarmed by deteriorating security in Afghanistan, began stepping up drone attacks on Taliban and al Qaeda militants in Pakistan last year.
There has been no let-up since President Barack Obama's administration took office in January, despite objections from Pakistan.
