At least 16 people were killed and more than two dozen wounded when a bomb blew up inside a bus in Peshawar, the main city of northwest Pakistan, officials said, with the toll expected to rise.
The explosion took place in Saddar, a busy shopping district, as the bus was picking up government workers to take them to their offices.
"At least 16 people were killed and more than 24 were wounded in a blast on a government employees' bus," senior police official Mohammad Kashif Zulfiqar told AFP.
