Pakistani police say a roadside bomb has killed at least two police officers and wounded three others in the country's restive northwest.
Senior police officer Shafiullah Khan said that the dead and injured police officers were guarding a key road on the outskirts of Peshawar city, capital of troubled Khyber Pakhtunkhwa Province, when the bomb detonated.
No one has claimed responsibility for the attack.
Pakistani militants routinely target government security forces in Pakistan.
This latest incident came a day after the country's new Prime Minister Nawaz Sharif was sworn in.
Sharif has called for peace talks with the Pakistani Taliban.
He has also opposed U.S. drone attacks in Pakistani tribal regions bordering Afghanistan.
