A year after the Taliban takeover, BBC correspondent Secunder Kermani visits the group's heartlands in southern Afghanistan to discover that peace comes at a price.

In a dusty patch of land next to the Helmand river, along what used to be one of the frontlines of the war, two teenage boys are locked in an embrace, trying to wrestle each other to the ground. Sitting in a wide circle, spectators look on eagerly as the early evening light begins to dim.

We're in Sangin district in southern Afghanistan, scene of some of the deadliest clashes of the past two decades. Much of the town is still rubble, though a number of houses are being rebuilt as residents return home, savouring their first taste of peace in years.

There are no women amongst the crowd: in this deeply conservative part of the country, they're largely kept behind closed doors. Many here supported the Taliban's insurgency against the former Afghan government and US-led forces that supported it, while others are simply relieved the violence that plagued their lives has finally come to an end.

"Life is very good now, people are happy," says Lalai, who has organised the wrestling match. "There's freedom and no problems," chimes in another man.

Everyone you speak to here has been affected by the war. "You won't find a single home in the district without at least two or three relatives martyred," Lalai tells us.
