The Taliban in Pakistan said it was behind the assault on a depot near Islamabad which left three people dead.
Pakistan has stopped Nato convoys crossing the Khyber Pass in response to a Nato air strike last week in which three Pakistani soldiers were killed.
Nato said on Monday it regretted the deaths but called for the crossing to be reopened.
Later on Monday, a US drone strike killed at least five militants in the town of Mir Ali in the troubled north-western Pakistani region of North Waziristan region, Pakistani intelligence officials said.
