Thought since the UK is the 'lead' nation in Helmand Province, this BBC News story might help: http://news.bbc.co.uk/1/hi/world/south_asia/7671118.stm
and this one from a different angle: http://news.bbc.co.uk/1/hi/world/south_asia/7674435.stm

Note the mention of an Afghan policeman shooting an US soldier, in Paktia Province.

Cannot find reports elsewhere, partly as other news dominates.
