DENPASAR, Indonesia—Indonesian and regional authorities heightened flight warnings around Bali’s Mount Agung on Sunday as the volcano’s eruptions sent a plume of volcanic ash and steam more than 6,000 meters into the skies above the popular holiday island.
Ash covered roads, cars and buildings near the volcano in the northeast of the island, while overnight a red glow of what appeared to be magma could be seen in photographs by Antara, the state news agency.
