The United States has apologised for the Nato helicopter attack inside Pakistan last week that killed at least two Pakistani soldiers and provoked the fury of the government in Islamabad. From Washington, Adam Brooks reports.
The American Ambassador in Islamabad Anne Patterson called the killings a terrible accident. An investigation found that US helicopters mistook Pakistani soldiers for militants and fired on them, killing two and injuring four. In response to the attack, Pakistan closed an important border crossing, and hundreds of trucks loaded with supplies for the military effort in Afghanistan are now held up inside Pakistan. The Americans will be hoping that this apology will reopen the border crossing.
In the latest incident, police in northwestern Pakistan say militants have attacked and destroyed a parked convoy of Nato fuel tankers bound for Afghanistan. The raid near Peshawar comes hours after the Pakistani Taliban said they carried out a similar attack further south on the outskirts of Quetta. A Nato spokesman has said military operations in Afghanistan were not being affected because there were already plenty of supplies inside the country.
