Islamabad- Pakistan's new President Asif Ali Zardari said Saturday his government would not allow any foreign nation to carry out attacks inside the country.

"We will not tolerate the violation of sovereignty and territorial integrity by any power in the name of combating terrorism," he told a joint session of the parliament, as the lawmakers thumped their desks in applause.

The warning came as the US has increased aerial attacks in Pakistan's tribal areas on the suspected hideouts of al-Qaeda and Taliban militants, who launch cross-border attacks on international forces in Afghanistan.

Repeatedly condemning the attacks, Islamabad has stressed that only its security forces have the right to strike the militants on its soil.

Zardari urged the government "to be firm in its resolve to not allow the use of its soil to carry out terrorists attacks against any foreign country."

He vowed to "root out terrorism and extremism wherever and whenever they may rear their ugly heads."

Zardari was elected president by an indirect vote by lawmakers of the two houses of parliament and four provincial assemblies in September 6.
