At least 10 police officers have been killed in an attack on a police station in north-west Pakistan.
Violence has escalated ahead of the country’s general elections this week.
Militants launched the attack at about 03:00 local time Monday (22:00 GMT Sunday), first with sniper fire, followed by grenades, according to police in the Draban region in Khyber Pakhtunkhwa province.
The exchange of fire lasted over two and a half hours, injuring nine others.
It is not yet clear who carried out the attack, but the area has seen strikes on government and security targets as well as civilians by the Pakistan Taliban, Islamic State and other militant groups for years.
