The re-eruption of a volcano on the island of Sumatra, Indonesia, may hamper international flight operations with smoke spewing up to over 2,000m into the air.
Mount Sinabang in North Sumatra province re-erupted at 6:30am Jakarta time on 30 August (23.30 GMT 29 Sunday).
Transport Ministry spokesman Bambang Ervan said the eruption has the potential to disturb international and domestic flight operations, according to Xinhua News Agency.
Most international flights to the main airport in the province and other airports on the island come from the north, said Ervan.
An official at the Meteorology and Geophysics Agency Agie Wandala confirmed the wind was blowing toward the north at the time of the re-eruption.
Mount Sinabung first erupted on 29 August for the first time after 400 years, forcing the evacuation of 11,000 people from the area.
