An eruption of Indonesia’s Mount Anak Krakatau ​caused the suspension of hundreds of flights at Jakarta’s main airport on ‌Sunday after some school activities and fishing were halted.

Soekarno-Hatta International Airport posted on Instagram that it had suspended flight operations until 9:30 a.m. (0230 GMT) due to volcanic ash.

The suspension, extending a halt ​that had been scheduled until 5:30 a.m., has affected 209 flights, including ​several international flights, Indonesia’s transportation ministry said.

Anak Krakatau has erupted since late ⁠on Friday, with volcanic ash detected at the airport early on Sunday, the ​ministry said in a statement.
