A dual Ukrainian-Russian citizen was arrested in France after suffering burns from an explosion at a hotel. The explosion occurred at a hotel in Val d'Oise, France, on Monday evening.

French officials are investigating whether the arrested person was trying to conduct a pro-Russian act of sabotage against a French facility that supported Ukraine's war efforts. The investigation found materials used to make explosive devices and that one of those devices had exploded. No other injuries were reported.

The U.S. officials said the device that exploded included the homemade explosive compound TATP, which has been used in some terror attacks in the last three decades.

The incident could be one of several recently documented examples of pro-Russian sabotage throughout Europe, according to U.S. officials.

U.S. and European officials say that Russia is conducting a sabotage campaign across Europe in an increasingly aggressive effort by President Vladimir Putin to undermine Western support for Ukraine, seeking to damage railways, military bases and other sites used to supply arms to Kyiv.

The incidents include an alleged Russian-backed arson attack on a Ukrainian-linked warehouse in the United Kingdom, a plot to bomb or set fire to military bases in Germany, attempts to hack and disrupt Europe’s railway signal network and the jamming of GPS systems for civil aviation, according to European and British authorities.

President Joe Biden is in France this week to mark the 80th anniversary of D-Day and will be honored by his French counterpart with a state visit on Saturday, including a military parade.

Security has been increased in the country as it prepares to host the Olympics at the end of July. Russia has been banned from the Paris Games over the war in Ukraine, and has mounted a secret influence campaign that seeks to frighten people away from the Games, according to a report.
