PESHAWAR: The Chaman border crossing at the Pak-Afghan border was closed on Wednesday for an indefinite period. The crossing points on the border had opened on March 7 and 8 following instructions from the federal government. “The border has been closed for an indefinite period,” said a Federal Investigation Agency (FIA) official. The official added that only valid passport holders were allowed to cross the border into Pakistan. More than 350 Pakistanis, stranded in Afghanistan, were allowed to enter Pakistan. Hundreds of Pakistanis, including transporters, traders, had been stranded in Afghanistan for the last 19 days. Meanwhile, Afghan refugees on their way home complained of slow clearing process. The government had decided to seal the border crossings for an indefinite period on February 16 in the wake of a suicide attack at Lal Shahbaz Qalandar’s shrine.
