LAHORE (Agencies) - Interior Minister Rehman Malik said that recent killings in Karachi were not a result of sectarian strife and involvement of a foreign hand could not be ruled out. Talking to the media at Allama Iqbal International Airport here Tuesday, he said foreign elements were attempting to shatter countrys peace through propagation of religious hatred and sectarianism. To a question, he said the PPP-led democratic governments action against NATO was in accordance with the sentiments of the people of Pakistan. He added that the federal government had suspended NATO supplies to Afghanistan through Pakistan and also issued notice to US authorities concerned for evacuation of Shamsi Airbase in Balochistan within 15 days. The interior minister said the international community must realise the fact that Pakistan had suffered a lot in the war on terrorism. To another question about former foreign minister Shah Mahmood Qureshi, he said a difference of opinion was the essence of democracy. Political success is always decided through a public vote and holding a gathering of people does not matter, he maintained. Malik also confirmed that notices have been sent to vacate the Shamsi Airbase and also denied reports that United Arab Emirates (UAE) requested Pakistan not to shut it down. Malik said that the NATO attack on Pakistani soldiers was uncalled for and the government has courageously responded to the US over the issue. He further said that decisions will now be taken according to the publics wishes. To a question, Malik said the US has made no request regarding the NATO supply or Shamsi Airbase.
