Nato helicopters have apparently begun firing on what they say are insurgent positions in Kabul, as the Taliban continues a series of attacks in the city.

Foreign embassies, Nato's HQ and the Afghan parliament all came under attack in the first major attack on the country's capital in more than six months.
