Police say 24 militants on motorcycles attacked the parked oil tankers Thursday earlier in the day . The tankers had been parked since Quetta shut down CNN supply routes last month . The airstrike was the latest blow to an already stormy partnership between the United States and Pakistan and plunged relations into perhaps the worst crisis since the two countries agreed to join forces in the fight against Islamist militancy after the 9/11 terrorist attacks . Closing the routes was a response to NATO airstrike that killed 7 Pakistani soldiers . No injuries reported in the attacks on tankers ; police say the attackers escaped .
