Soldiers were this month flown into Peochar valley, a stronghold of Maulana Fazlullah who has led a Taliban uprising to enforce sharia law in Swat. It remains unclear how much of the area remains under militant control.
Neither is it possible to independently confirm information released by the army because the conflict area has been declared a closed military zone.
Pakistan claims more than 1,200 militants have been killed in the conflict but there has been little official word on civilian casualties during the month-long offensive in the northwest.
'In last 24 hours, 28 miscreants-terrorists were killed and seven were apprehended in various areas of Swat during exchange of fire with security forces, while five soldiers and two civilians were injured,' the military said.
Medical officials, journalists and aid workers have been unable to confirm death tolls issued by the military, but many of those displaced by the conflict have told of relatives being killed.
Some of the heaviest recent fighting seems to have taken place in the northern Swat town of Bahrain, which security forces entered yesterday.
The military said security forces had recovered 12 'UN registered vehicles' and destroyed militant hideouts.
Around 2.4 million people have fled fighting as soldiers struggle to wrest back the western Swat and two nearby districts from the Taliban, who last month advanced to within 100km of the capital, Islamabad.
