Marines are starting a push to clear the last pockets of Taliban insurgents from Marjah.
More than 100 Marines and their Afghan counterparts are pushing into a neighborhood they say is the last significant stronghold of insurgents. Marine commanders say they believe about 100 militants have regrouped in a 28-square-mile area.
Troops haven't met the stiff resistance they expected. Some fleeing Afghans say Taliban militants said they were planning a large attack, while others say they haven't seen a militant in days.
In the past week, Marines have come under heavy fire each time they skirted the zone.
A Marine spokesman says he expects there will be a spike in fighting as troops move into the final pockets.
Captain Abe Sipe says "We by no means think that this is over."
