CHAMAN, Pakistan -- Security officials say trucks carrying NATO supplies will resume their routes through Pakistan to Afghanistan on Thursday, following Islamabad's agreement to end its seven-month blockade.

The Pakistani officials say two trucks were cleared by customs and security officers at the border Wednesday, but the station closed at sunset before they could cross.

Pakistan agreed Tuesday to reopen the NATO supply line after the U.S. said it was sorry for American airstrikes that killed 24 Pakistani troops in November.

The security officials say the two trucks that have been cleared at the Chaman border crossing in southwestern Baluchistan province are expected to move into Afghanistan when the border opens at 9 a.m. Thursday.

The officials spoke on condition of anonymity because they were not authorized to talk to reporters.
