Pakistan's president warns the US on strikes against Pakistan, saying the violation of the country's border would not be tolerated.

Pakistani Government sources were quoted by the Dawn News channel on Monday as saying that Pakistani President Asif Ali Zardari had told British officials on the same day that violations of Pakistan's frontiers would not be tolerated.

During a meeting with visiting British Permanent Under Secretary for Foreign Affairs Peter Ricketts and Permanent Under Secretary of Home Office, David Normington, Zardari said Pakistan's sovereignty and territorial integrity must be respected.

Zardari was referring to recent border missile strikes by US forces on its border tribal areas.

The US has long carried out missile strikes against suspected al-Qaeda and Taliban hideouts in northwest Pakistan, but a recent surge in the attacks has prompted official Pakistani condemnation which has been yet to no avail.

In the past month, US forces have carried out eight missile strikes by pilotless drones and a commando ground raid on the Pakistani side of the border with Afghanistan, creating new tensions between the two countries.

Islamabad says the strikes are an infringement of its sovereignty and are counterproductive in the battle against militants.

Pakistani civilian and military leaders have frequently protested over the US incursions into Pakistan's tribal region, with Prime Minister Syed Yousuf Raza Gilani terming the attacks as an 'act of terrorism'.

US Predator drones armed with Hellfire missiles along with ground raids, have killed dozens of Pakistani civilians in recent months.

UN Chief Ban Ki-moon has also urged the US to avoid incursions into Pakistani territories, emphasizing respect for the country's sovereignty.
