Satellite imagery showed the ash plume had exited Indian airspace by 10:30pm, the India Meteorological Department said. The cloud, travelling at altitudes between nine and 15 kilometres, had passed over Gujarat, Rajasthan, the National Capital Region, Uttar Pradesh, Bihar and the northeast before advancing toward China. Airlines cancelled and delayed dozens of flights as a precautionary measure after the Directorate General of Civil Aviation issued an advisory warning of possible hazards to aircraft engines from volcanic ash. Air India cancelled seven flights on Monday and four more on Tuesday, including Chennai-Mumbai and Hyderabad-Delhi services.

Key air routes across northwest India were affected. IndiGo's Kannur-Abu Dhabi service was diverted to Ahmedabad to avoid the plume. P11...
