ISLAMABAD (Reuters) - U.S. National Security Adviser Susan Rice met Pakistan's prime minister on Sunday to press concerns over attacks launched by militants based in Pakistan, officials said.

The visit to Islamabad, part of an Asian tour that included an earlier stop in China, comes amid uncertainty over whether the United States will release $300 million in military aid to Pakistan.
