Brussels, Mar. 6 : Perturbed by the recent terror attack on the Sri Lankan cricket team in Lahore, US Secretary of State, Hillary Clinton has said that the situation in Pakistan is threatening, as it is facing serious internal security challenges.

Talking to NATO foreign ministers in a meeting here, Clinton compared the Lahore attack with the terror attacks on Mumbai, and termed it as an `eerie replica'of the 26/11 incident.

Pointing towards the insurgency along the Pakistan-Afghanistan border, she stressed on the need of a regional approach to counter the issue of terrorism along the Pakistan-Afghanistan border.

Clinton also informed that a high-level conference on Afghanistan will be convened later this month.

"The United States proposes a ministerial-level conference on Afghanistan and the broader regional challenge on March 31," The Daily Times quoted Clinton, as saying.

Clinton, however, did not mention the venue of the conference.

She also supported the Obama administration's decision to send in more troops to Afghanistan to facilitate the on going `War on terror' in the region.

"We must add resources to address the serious situation on the ground right now. President Obama has committed 17,000 more troops, and we appreciate that some countries are giving more," Clinton said.

Washington's decision to send in more troops to Afghanistan is seen as a preparation to what may be termed as a `final assault' to root out Al-Qaeda and the Taliban from their stronghold. (ANI)
