Three RAF Chinook helicopters sent to Nepal to help the aid effort in the country are to return to the UK having not been used, the government has said. The CH47 Chinooks left the UK two weeks ago to help transport “life-saving aid supplies” and reach stranded victims “in desperate need” of help. But the helicopters have been grounded in Delhi, in India, for the past week. The Ministry of Defence said it was “disappointed”, saying the decision had been made by the Nepalese government. An MoD spokesman said the Nepalese government, while thanking the UK for the offer, had said the helicopters will not take part in the relief effort.
