The facility is available both at Islamabad International Airport and Chakala Airbase where FIA officials have been positioned to facilitate the visitors without any hassle, he was quoted as saying by The Nation newspaper.

Under the decision taken at a high-level meeting in the interior ministry, all the visitors will be given one-week permission to stay. However, this period could be extended on request.

Over 45 special foreign flights carrying relief goods have so far arrived in the country in response to Islamabad's call for international help to the quake affected areas.
