"Unless the reaction cools down and we make sure that the supply line is secured, we cannot reopen it," The News quoted Basit, as saying.
"It's just because of security reasons. There's no timeframe. I think it should be done soon," he added.
Basit pointed out that although Pakistan was responsible for the safety of the NATO supply line, its tankers were burnt at different places because of public resentment in the country.
Meanwhile, a Pakistani military official has disclosed that a joint investigation of the incident has been started by Pakistan and NATO.
"In such a situation, allowing these trucks to carry on with their journey would be inviting more attacks so there's no need to rush," added the official.
Last week, the three Pakistani army men were killed in an early morning air strike by NATO helicopters at a military post in Kurram Agency, reacting to which, the nation had suspended supply convoys along the Khyber Pass route.
