Several Western embassies here on Wednesday received letters containing suspicious powder and threats to poison NATO soldiers in Afghanistan, Pakistan officials said.
Islamabad police chief Bani Amin said that embassies had received small packets containing black powder, which had been sent for laboratory analysis.
The letters said ‘poison’ would be hidden in NATO supplies should Pakistan decide to lift a nearly six-month blockade on supplies for American and NATO troops fighting the Taliban in neighbouring Afghanistan.
Senior Pakistani security officials said that the French embassy, and the Australian and British High Commissions had received suspicious packages.
"Embassies have received one sachet each. The problem is that it is in a meagre quantity and difficult even to test. It seems somebody has committed some mischief. We are sending it to a laboratory," Amin said.
