At least 22 police and 76 Taliban died and an undetermined number were wounded in combat in the eastern province of Nangarhar, an unnamed Afghan official told the AIP news agency Friday.

The official said, without providing further details, that the clashes began Friday in the Shirzad district and went on until Saturday.

AIP also cited a Taliban account that said 84 police were killed, though the insurgents tend to exaggerate.

These casualties among members of the police corps increase the number of police killed in Afghanistan over the past four months to 2,748, according to figures recently announced by the Interior Ministry.

The Afghan conflict is going through one of its bloodiest moments in the almost 12 years following the U.S. invastion that toppled the Taliban regime.

Troops of the NATO-led International Security Assistance Force will complete their withdrawal next year.

In the first six months of 2013, some 95 ISAF soldiers died, the fewest since 2006, when 75 members of the armed forces lost their lives in the same period, the independent portal iCasualties said.

At the same time, during the first half of 2013 in Afghanistan, 1,319 civilians were killed, a 14 percent increase over the first six months of 2012, according to a U.N. report. EFE
