Marines assault Taliban town in Afghanistan

DAHANEH, Afghanistan – Helicopter-borne U.S. Marines backed by Harrier jets stormed a Taliban-held town in southern Afghanistan before dawn Wednesday, the launch of a new operation to uproot Taliban fighters from a longtime base and provide security for next week's presidential election.

The troops exchanged heavy fire with insurgents, killing at least seven in an offensive they hoped would also cut Taliban supply lines and isolate their fighters.

Casualties have mounted as U.S. and NATO troops ramp up military operations following President Barack Obama's decision to deploy 21,000 more American forces to Afghanistan this year to cope with the rising Taliban insurgency. 

Last month, U.S. and NATO deaths from roadside and suicide bomb blasts in Afghanistan soared six-fold compared with the same month last year, as militants detonated the highest number of bombs of the eight-year war, according to figures released Tuesday.

Martin confirmed suspicions among the Marines that the fierce resistance indicated that the Taliban had been tipped off about the operation beforehand. "I'm pretty sure they knew of it in advance," he said. 

Once the second largest-town in Helmand, Naw Zad has been almost emptied of its 30,000 inhabitants after three years of near-constant fighting. Taliban lines begin barely a mile (a kilometer) from the Marines' forward operating base, set amid minefields with hundreds of homemade explosives. By occupying Dahaneh, the Marines say they can outflank the insurgents in Naw Zad valley and isolate them in woods and mountains
