The Romanian government vowed new measures against Moscow after fragments from a Russian drone strike on Ukraine landed on its territory overnight, the latest in a string of cross-border incidents.

In a post on X, Romanian Foreign Minister Oana Toiu said the debris fell in an inhabited area following Russian strikes on Ukrainian commercial ports, calling the assault “another reckless attack on Ukraine with consequences on Romanian territory.”

“These actions are part of a clear pattern in Russia’s war of aggression,” Toiu wrote. “We will not hesitate to increase the price Russia pays for such reckless and illegal actions.”

According to a statement from Romania’s defense ministry, radar systems detected groups of drones near the country’s airspace during the night of November 10–11, prompting the preventive activation of air defense systems.

Around one in the morning, authorities reported that a drone had crashed near the Romanian village of Grindu, about five kilometers south of the frontier with Ukraine.

Due to poor weather conditions in the southeast, fighter jets on standby were unable to take off.

Toiu added that Romania, the EU and the U.S. have already imposed sanctions with “important impact” on Russia and are now preparing additional measures to raise the cost of aggression.
