July 19 (Reuters) - A fire broke out at the military training grounds in the Kirovske district on the Crimean Peninsula, the Moscow-backed governor of Crimea said on Wednesday.

The fire forced the closure of the nearby Tavrida Highway, Russian-installed Governor Sergei Aksyonov of Crimea said on the Telegram messaging app.

Earlier, the RBC-Ukraine news agency reported that there were explosions on the military training grounds. Reuters could not independently verify the report. (Reporting by Lidia Kelly in Melbourne; Editing by Jacqueline Wong)
