Haley came out in support of President Donald Trump's decision to block USD 255 million military aid to Pakistan.
"There are clear reasons for this. Pakistan has played a double game for years," Haley told reporters at a news conference at the UN headquarters in New York yesterday.
"They (Pakistanis) work with us at times, and they also harbour the terrorists that attack our troops in Afghanistan. That game is not acceptable to this administration," Haley said.
The Trump Administration expects far more co-operation from Pakistan in the fight against terrorism, she said.
"Trump is willing to go to great lengths to stop all funding from Pakistan as they continue to harbour and support terrorism," Haley said in her opening remarks during her first news conference of the year.

Haley said the aid issue is connected solely to Pakistan's harbouring of terrorists.
