S.Africa police order striking miners to disperse

JOHANNESBURG, Aug 16 (Reuters) - South African police

ordered thousands of illegally striking miners armed with

machetes and sticks to lay down their weapons and leave Lonmin's

Marikana platinum mine on Thursday or face an

assault by security forces.

"Today is unfortunately D-day," police spokesman Dennis

Adriao said. "It is an illegal gathering. We've tried to

negotiate and we'll try again but if that fails, we'll obviously

have to go to a tactical phase."

Ten people, including two policemen, have died in nearly a

week of fighting between rival worker factions at the mine, 100

km (60 miles) northwest of Johannesburg, the latest platinum

plant to be hit by fallout from an eight-month union turf war.

On Wednesday, up to 3,000 police officers, including members

of an elite, camouflage-wearing riot control unit backed by

helicopters and horses, confronted several thousand protesting

rock-drill operators massed on a rocky outcrop near the mine.

There were no clashes although police described the

situation as tense.

The unrest forced Marikana's London-headquartered owner

Lonmin to halt production this week at all its South African

operations, which account for 12 percent of global platinum

output.

The Marikana strikers have not made their demands explicit,

although much of the bad blood stems from a turf war between the

National Union of Mineworkers (NUM), the dominant union for the

last two decades, and the newer Association of Mineworkers and

Construction Union (AMCU), which is on a big recruitment push.

At least three people were killed in a similar round of

fighting in January that led to a six-week closure of the

world's largest platinum mine, run by Impala Platinum.

That helped push the platinum price up 15 percent.

South Africa is home to 80 percent of the world's known

platinum reserves, but rising power and labour costs and a sharp

drop in the price of the precious metal this year has left many

mines struggling to keep their heads above water.
