The Pakistani Taliban has claimed a series of attacks targeting police officers from Kohat in the northwest to Lahore in the east.
They are the latest in a surge of attacks in the country as the government prepares for a ground offensive into South Waziristan, a key Taliban stronghold.
The Taliban have said they will fight to the death and bring the battle to Pakistan's major urban centres.
