The government expressed the hope on Sunday that its growing row with the United States over US functionary Raymond Davis will not scuttle its crucial talks with Washington and Kabul on efforts to stabilize Afghanistan. Tensions have been rising between Pakistan and the United States over the case of Davis, a U.S. consular employee who shot dead two Pakistanis last month in what he said was an attempted robbery. The U.S. State Department on Saturday said a meeting scheduled this month in Washington among U.S., Afghan and Pakistani officials had been postponed, citing "political changes" in Pakistan.
