The massive offensive was aimed at establishing Afghan government authority over the biggest southern town under militant control and breaking the Taliban grip over a wide area of their southern heartland.
Maj. Gen. Nick Carter, NATO commander of forces in southern Afghanistan, said Afghan and coalition troops, aided by 60 helicopters, made a "successful insertion" into Marjah in southern Helmand province. He said the operation was going "without a hitch."
Thousands of British, U.S. and Canadian troops also swept into Taliban areas to the north of Marjah, seeking to clear a wide swath of villages that had been under Taliban control for several years.
No coalition casualties had been reported more than 12 hours after the initial airborne assault, but NATO said three U.S. soldiers were killed Saturday in a bombing elsewhere in southern Afghanistan.
At least 20 insurgents were reported killed in the Helmand operation, said Gen. Sher Mohammad Zazai, the commander of Afghan forces in the region. Troops have recovered Kalashnikov rifles, heavy machine guns and grenades from 11 insurgents captured so far.
The few civilians who ventured out to talk to the Marines said teams of Taliban fighters were falling back deeper into the town, perhaps to try to regroup and mount harassment attacks to prevent the government from rushing in aid and public services
- a key step in the operation.
The long-awaited assault on Marjah is the biggest offensive since the 2001 U.S.-led invasion of Afghanistan and is a major test of a new NATO strategy focused on protecting civilians. The attack is also the first major combat operation since President Barack Obama ordered 30,000 U.S. reinforcements here in December to try to turn the tide of the war.
President Hamid Karzai called on Afghan and international troops "to exercise absolute caution to avoid harming civilians," including avoiding airstrikes in areas where civilians are at risk. In a statement, he also called on insurgent fighters to renounce violence and reintegrate into civilian life.
A Taliban spokesman insisted the insurgents were still resisting the allied assault and that the town remained under their control.
"The Taliban are there and they are fighting. All of Marjah is still under Taliban control," Qari Yousef Ahmadi told The Associated Press by phone. He declined to say how many Taliban fighters remained in the town but dismissed NATO accounts as "propaganda."
Lt. Col. Brian Christmas, commander of the 3rd Battalion, 6th Marines, said U.S. troops faced sustained gunbattles in four areas of the town, including the western suburb of Sistani where India Company faced "some intense fighting." To the east, Kilo Company was inserted by helicopter but was then "significantly engaged" as the Marines fanned out from the landing zone.
But the greatest threat came from the extensive network of mines, homemade bombs and booby traps that ground forces encountered as soon as they crossed a major major canal into the town's northern entrance.
Insurgents appeared to have withdrawn from their frontline positions but left boobytraps and explosives in their abandoned positions and in the network of canals built by the Americans in the 1950s and 1960s. Marines safely set off numerous bombs, as the sound of strong detonations reverberated through the dusty streets.
"It's just got to be a very slow and deliberate process," said Capt. Joshua Winfrey of Stillwater, Okla., a Marine company commander.
The bridge over the canal into Marjah from the north was so rigged with explosives that Marines erected temporary bridges to cross into the town.
Lance Corp. Ivan Meza, 19, was the first to walk across one of the flimsy bridges.
"I did get an adrenaline rush, and that bridge is wobbly," said Meza, a Marine combat engineer from Pismo Beach, California, who is with the 1st Platoon, Lima Company, 3rd Battalion, 6th Marines.
Several civilians hesitantly crept out of their compounds as the Marines slowly worked through a suspected mine field. The Marines entered compounds first to make sure they were clear of bombs, then called in their Afghan counterparts to interview civilians inside.
