Plea to Wikileaks over documents
The US government has pleaded with website Wikileaks not to post any more classified documents about the Afghanistan war, saying national security was at risk.
White House press secretary Robert Gibbs said the leak of 90,000 secret military documents has already jeopardised the lives of Afghans working with the US and its allies.
He said the Taliban has declared it will comb the material for the names of people who have co-operated with international forces in Afghanistan.
Mr Gibbs said the release of another 15,000 documents reportedly still held by Wikileaks would do more damage.
He added that the White House "can do nothing but implore the person who has the documents not to post any more".
The plea came on the day that three more US troops were killed in Afghanistan, bringing the US death toll for July to at least 66 and making it the deadliest month for American forces in the nearly nine-year-war.
Nato said one service member died following an insurgent attack and two others were killed in a roadside bombing.
Earlier the US confirmed three other American service members died in two separate blasts in southern Afghanistan on Thursday.
In Kabul, police fired weapons into the air on Friday to disperse a crowd of angry Afghans who shouted "death to America," hurled stones and set fire to two vehicles after an SUV was involved in a traffic accident that killed four Afghans on the main airport road, according to the capital's criminal investigations chief, Abdul Ghaafar Sayedzada.
SUVs often are associated with foreigners, but it remained unclear who caused the accident because the occupants fled the scene. Afghan police, some carrying riot shields, converged on the area, firing warning shots into the air to disperse the protesters. Sayedzada said the crowd burned two foreigners' vehicles, causing heavy black smoke to rise from the scene.
