Authorities in Monaco have detained a suspect in connection with the bombing that rocked the principality on Tuesday, killing three people and injuring dozens more, officials confirmed late Wednesday.
Bombing Details and Immediate Response
The explosion occurred near the Monte Carlo Casino at approximately 6:30 p.m. local time, shattering windows and sending panic through the crowded tourist district. Emergency services rushed to the scene, evacuating nearby buildings and cordoning off the area. The blast killed two bystanders and one security guard, while 42 others were treated for injuries, 12 of whom remain hospitalized in serious condition.
According to Monaco's Public Security Department, the device was believed to be a homemade bomb packed with shrapnel, detonated remotely. Investigators recovered fragments of a mobile phone at the scene, which they suspect was used to trigger the explosion.
Suspect Apprehension and Investigation
The suspect, a 34-year-old French national identified as Marc Dufour, was arrested at a hotel in Nice, France, early Wednesday morning following a joint operation between Monégasque and French police. Dufour had been under surveillance since Tuesday night after his vehicle was spotted on CCTV near the casino shortly before the blast.
“We have taken a significant step forward in this investigation,” said Monaco's Chief Prosecutor, Marie Leclerc, in a press conference. “The suspect is currently in custody and is being questioned. We are working closely with French authorities to determine any accomplices or broader network.”
Impact and Security Measures
The attack has sent shockwaves through Monaco, a wealthy city-state known for its low crime rate and high-profile events. The principality has raised its security alert to the highest level, with increased police patrols and checkpoints at key locations. The Monte Carlo Casino and nearby hotels have been closed indefinitely as the investigation continues.
Monaco's Prince Albert II issued a statement condemning the attack, calling it “a cowardly act of violence that will not undermine our way of life.” He expressed condolences to the victims' families and pledged full support for the investigation.
International Reactions and Broader Context
The bombing has drawn international condemnation, with leaders from France, Italy, and the European Union offering assistance. The attack comes amid heightened tensions across Europe, with several countries on alert for potential terrorist threats. However, authorities have not yet confirmed a motive or claimed responsibility.
“This is a stark reminder that no country is immune to terrorism,” said EU counter-terrorism coordinator Gilles de Kerchove. “We stand with Monaco and will provide all necessary resources to bring those responsible to justice.”
The investigation remains ongoing, with forensic teams analyzing evidence from the blast site and reviewing surveillance footage. Police are urging anyone with information to come forward.
