The United States suspended a $800 million aid to Pakistan amid the "complicated relationship" between the two countries, White House Chief of Staff , William Daley said on Sunday.
Daley's statement comes as the U.S.-Pakistani relations are worsening after al Qaeda's leader, Osama bin Laden, who was killed in his Pakistani compound during the U.S. raid on May 2.
"Right now Obviously there's still a lot of pain that the political system in Pakistan is feeling by virtue of the raid that we did to get Osama bin Laden. We have no regrets over (that raid)," Daley said in an interview with ABS News.
The U.S. officials suspected that Pakistani authorities knew about bin Laden's whereabouts, while Pakistan slammed the United States for carrying out a secret military raid without Islamabad's consent.
The $800 million is about a third of the annual U.S. military aid sent to Pakistan to assist counterterrorism operations as well as to provide the country with military equipment such as radios, night-vision goggles and helicopter spare parts.
"It's a complicated relationship and a very difficult complicated part of the world," Daley said. "They've taken some steps that have given us reason to pause on some of the aid which we're giving to the military, and we're trying to work through that."
