The measures, along with the deployment of four additional U.S. F-16 fighter jets and an expanded no-fly zone, are a sign of growing concern in Romania and the broader NATO alliance that the Ukraine war could spill over into its territory.

Soon after pulling out of the Black Sea grain deal on July 17, Moscow began targeting Ukrainian ports and warehouses along the Danube, in an apparent attempt to choke off the main alternative route for Ukraine's agricultural exports.

Isolated incidents of drone parts landing in Romania underline the risk of a misunderstanding, or worse, between Russia and NATO, prompting Romanian armed forces to increase security in the area to protect civilians, the two sources said.

The army has built two bomb shelters in the small hamlet of Plauru, just a few hundred metres from Izmail, and residents in the wider area are sent alerts on mobile phones when Russian drones are detected heading in their direction.

From mid-September, the ministry also expanded a no-fly zone along a section of the border with Ukraine to up to 30 km (20 miles) inside Romania and to a height of 4,000 metres as a deterrent against Russian drones entering Romanian air space to reach enemy targets.

Romanian defence ministry spokesman Constantin Spinu also said there was no indication Russia was targeting Romania, but that the nature of attacks on Ukrainian territory nearby made it virtually impossible to prevent all breaches.
