Pakistan blocked a major NATO supply line into Afghanistan today, in apparent retaliation for a cross-border helicopter attack. A pair of NATO helicopters opened fire on a border village in Pakistan’s Kurram region this morning, killing three Frontiers Corps troops, Pakistani security tells Reuters. Within hours, roughly 100 NATO trucks were lined up waiting to cross the border, the AP reports. NATO says it is investigating the incident.
“We will have to see whether we are allies or enemies,” Pakistan’s Interior minister said of the attack, without mentioning the blockade. But a senior security official confirmed that supplies have been stopped. “It has been done locally,” he said. The blockade, which has the potential to cripple the Afghan war effort, marks a new high in US-Pakistani tensions, and comes just as CIA chief Leon Panetta arrived in Pakistan for a previously planned meeting with the head of the ISI.
