Pakistan has deployed security forces at the country's largest state-run telecom company and detained scores of union members, following a call for a nationwide strike against government plans to privatize it. Authorities have confirmed dozens of arrests, and say troops have taken control of key facilities of the firm, Pakistan Telecommunication Company Limited, in all major cities. Sunday's action follows a government announcement Saturday to sell off 26 percent of shares of the company on June 18th. Union leaders criticized the decision and threatened industrial action unless the privatization plan is withdrawn by Wednesday. But the authorities say the decision is irreversible and warned that those who try to damage national assets will be dealt with severely.
