The Obama administration says Pakistan is considering pulling out of an international conference on Afghanistan next week as a result of the NATO airstrikes that killed 24 Pakistani soldiers.
State Department spokesman Mark Toner says Pakistani officials have informed the U.S. they are reviewing their participation. He acknowledged that the weekend incident was a setback for U.S.-Pakistani relations.
The conference next week in Bonn, Germany, seeks a strategy to stabilize Afghanistan a decade after al-Qaida used the country as a base to launch the 9/11 attacks and U.S.-backed forces overthrew the Taliban.
Toner urged Pakistan to attend.
He also said Monday that investigations were under way into the NATO strikes. He said Washington and Islamabad will have to work through the difficulties in their "vitally important" relationship.
