A bomb has gone off in a market in north-western Pakistan, killing at least 15 people, police say.
The explosion took place at a bus terminal in the main bazaar in the town of Kohat, close to Pakistan's border regions with Afghanistan.
Police say a suicide bomber carried out the attack.
The Pakistani Taliban claimed responsibility for two blasts at a government compound in the border area on Monday which killed 40 people.
A police spokesman in Kohat said the bomber had approached the door of a bus carrying passengers to the nearby tribal district of Orakzai and set off his explosives.
Officials say the bus terminal was packed with commuters, and the number of casualties could rise.
Local journalists say many shops in the market were also damaged.
Kohat is close to Pakistan's border regions with Afghanistan, where Taliban militants are strong.
They have carried out scores of suicide bombings in recent years, despite government offensives against some of their strongholds. BBC News
