The policing powers Rangers have been extended by 90 days in Karachi.
The Sindh government approved the extension on Friday under Section 4(2) of the Anti-Terrorism Act, 1997. The act requires provincial governments to request the federal government to order deployment of armed forces if it deems necessary to combat terrorism.
The Rangers will perform their duties from April 6 to July 4, said a summary sent to the Interior Ministry.
The extension was announced after the Rangers rejected a report by BBC Urdu that claimed that they have been called to the border and relieved of their duties in Sindh.
The paramilitary force said that there was no truth in the report. It said that there has been no change in its duty in Karachi or interior Sindh.
