(Reuters) -A Ukrainian drone attack targeting Moscow forced the closure of two of the key airports serving the capital, Russian authorities said early on Sunday.

Russia air defence units destroyed nine Ukrainian drones heading towards Moscow by 0400 GMT, Mayor Sergei Sobyanin said on the Telegram messaging app.

Emergency services were dispatched to the sites where drone debris fell in the overnight attack, Sobyanin said. He did not report any immediate damage.

A Ukrainian drone attack also sparked a short-lived fire at the Azot chemical plant in the Tula region, injuring two people, and seven drones were destroyed over the Kaluga region, regional governors said. Both regions border the Moscow region to the south of the capital.
