The talks focussed on bilateral relations, defence and anti-terrorism cooperation and the regional situation, Pakistani officials said.

Rocca also signed a memorandum of understanding with Pakistan minister for economic affairs Hina Rabbani Khar, under which US will provide 147.6 million dollars to improve education and health services, officials said.

She also met with Pakistani foreign minister Khurshid Mahmud Kasuri and MPs from both ruling and opposition parties at Pakistan's federal parliament.

However Rocca's expected meeting with opposition leader Fazalur Rehman, whose alliance of Islamic parties has called for countrywide protests over alleged abuse of the Koran at Guantanamo Bay, did not take place.

"We are not turning down the offer to meet her but we would have liked a one-on-one meeting that would have given us an opportunity to explain many things," Rehman told AFP.

Protests erupted across the Muslim world after a May 2 report in Newsweek magazine that US investigators had found that interrogators at the US detention centre in Guantanamo Bay threw a Koran in a toilet to rattle Muslim inmates.
