Islamabad: Pakistan has strongly condemned the US drone strike in North Waziristan on May 16 that killed at least five people and has called for cessation of such strikes.

 “A drone strike on May 16, 2015 resulted in a number of casualties in the Mana area of North Waziristan agency,” said the Foreign Office in a statement.

"Such strikes are a clear violation of Pakistan’s sovereignty and territorial integrity," Foreign Office spokesman Qazi Khalilullah said.

Six suspected militants were killed and two others wounded in a US drone strike in the remote Shawal Valley in the North Waziristan tribal region on Saturday.

The spokesman said these drone attacks generate distrust among the local populace at a time when Operation Zarb-i-Azb is moving ahead decisively and the focus of the government is shifting towards rehabilitation of the civilian population.
