Six foreign soldiers killed in Afghanistan

Afghanistan's Taliban-infested south on Sunday, days before the White House publishes a review of US military strategy in the increasingly deadly war.
Despite record numbers of coalition deaths and talk that the Taliban's reach is spreading, the US assessment is likely to endorse the current strategy amid claims of some battlefield success in the highly volatile south.
But critics say the mounting death toll is indicative of a strengthening insurgency and that it is time to negotiate with the militants to end nine years of violence that is only getting worse.
Nato would not give further details of the latest incident, one of the deadliest single attacks in recent months on foreign soldiers, and would not reveal the nationalities of the dead, in line with policy.
The attack took to 692 the number of foreign soldiers killed so far in 2010, the bloodiest year by far in the conflict, according to an AFP tally based one kept by icasualties.org. In 2009, 521 coalition troops died.
