Russian Defence Ministry on Tuesday said four Ukrainian drones were intercepted before they could target the nation.

"Earlier today, the Kyiv regime’s attempt to carry out a terrorist attack using drones was foiled," the ministry was quoted as saying by TASS.

"Two drones, which were detected by air defence facilities on duty and suppressed by electronic warfare systems, crashed over the territory of the Bryansk Region [in west Russia]," it said. "The other two drones were detected and destroyed by air defences above the territory of the Moscow Region."

"No casualties occurred as a result of these foiled terrorist attacks," the ministry added.

Earlier in the day, Moscow Mayor Sergey Sobyanin wrote on his Telegram channel that Russia’s air defence forces had shot down two strike drones approaching Moscow in the early hours of Tuesday, reports the news agency.
