ISLAMABAD - Pakistan has spelled out in no uncertain terms that US drone aircraft strikes against militants inside its territory must stop, but Washington is not listening, the country's foreign minister said.

"On drones, the language is clear: a clear cessation of drone strikes," Hina Rabbani Khar said.

"I maintain the position that we'd told them categorically before. But they did not listen. I hope their listening will improve," she told Reuters in an interview late on Wednesday.

The attacks by the unmanned aircraft from Afghanistan, which US officials say are highly effective against militants, fuel anti-American sentiment in Pakistan because they are seen as violations of sovereignty that inflict civilian casualties.
