Timika – The Indonesian subsidiary of US mining giant McMoRan said on Monday it had resumed operations after a two-week suspension caused by fighting among workers.

Work was halted last month after employees complained that a deal struck in December – which ended a three-month strike over wages and conditions – was not being implemented properly my management, with some strikers not being paid.

The company closed the mine, saying some workers who participated in the strike had "engaged in acts of violence and intimidation against non-striking workers and supervisory personnel." Three workers were arrested by police over the violence.

But on Monday Freeport Indonesia spokesman Ramdani Sirait told AFP: "The workers' union and the company management agreed last week to mobilise all workers to return to work today." "Hopefully everything will go back to normal again," he added.

Freeport did not give details on what led to the latest agreement, but workers' union spokesman Virgo Solossa said: "Freeport had promised to give salary to those who had not received their pay."

However, Solossa defended the workers, telling AFP: "Those who didn't receive their salary were upset and took it out on their colleagues who received their pay. "We also want the three workers to be released as I'm afraid that if they are prosecuted, it could lead to another protest," he said.

The workers agreed to return to the mine in mid – December after negotiating a 37 percent increase their wages, which started at $1.50 an hour for unionised members and better conditions for contractors.

The company slashed production by 50 percent when 8,000 of Freeport's 23,000 workers went on strike last year. The strike at the mine triggered a spate of violence, with at least eight people killed in ambush attacks and clashes with police in the already troubled province.
