A volcanic eruption in eastern Indonesia has snarled air traffic for Bali visitors. Overseas tourists have been left stranded as a massive ash cloud grounds international flights.

Travelers from abroad faced a string of cancellations at Bali's international airport. 115 international and domestic flights were grounded on Wednesday, with many airlines doing the same for Thursday.

A tourist said, "I have to take another vacation day, I'm supposed to go back to work right away." Another tourist said, "I've got to go home for three kids, so hopefully we can catch a flight to get out of here today."

The initial eruption occurred at Mount Lewotobi Laki-laki on the island of Flores on November 3. It left 9 people dead.

The volcano has since erupted repeatedly, spewing a column of hot ash into the sky. A volcanic alert remains at the highest level. More than 13,000 people have been forced to evacuate.
