DAWN.COM | Pakistan | Iran shuts its border with Pakistan Iran shuts its border with Pakistan A Pakistani official confirmed on Sunday that the Iranian authorities had closed the border. Iran had closed the border partially on Thursday after a suicide bomber attacked a mosque in Zahedan, but ordered complete closure on Saturday. Sources said that Iranian authorities had also tightened security along the border. The Iranian move has caused suspension of trade through the area. There was no trade now, the sources said, adding that people belonging to tribes living on the two sides of the border were facing enormous difficulties. The Iranian border authorities have also stopped issuing temporary permits to people settled on both sides of the border. The suspension of trade has resulted in an acute shortage of foodstuff coming from Iran.
