India says at least twenty of its soldiers were killed in a clash with Chinese forces, raising the original number of casualties it first reported. The hand-to-hand fighting took place along a disputed border in the Himalayas. China has accused India of a ‘provocation’ and has not disclosed if any of its troops were killed. Tensions between the two sides have been building over the last month. This is the first incident with fatalities in more than 40 years.
