Italian police arrest country's most-wanted mafia boss

• Dozens of police were involved in the operation to arrest Messina Denaro at a private clinic in Sicily where he was receiving treatment for an undisclosed medical condition, according to BBC.

What they're saying: "A great victory for the state which demonstrates that it does not give up in the face of the mafia," Italian Prime Minister Giorgia Meloni said in a translated post on social media on Monday.

• "My warmest thanks, together with those of the entire government, go to the police forces, and in particular to the Ros dei Carabinieri, to the national anti-mafia prosecutor and to the Palermo prosecutor for the capture of the most significant exponent of mafia crime," Meloni added.

The big picture: Messina Denaro is now set to be imprisoned over two bombings in Sicily in the early 1990s, including one that killed the country's two top anti-Mafia prosecutors at the time.

• He was also convicted of kidnapping, torturing and killing the 11-year-old son of another mafioso who became a state witness.
• He oversaw several other crimes for the Cosa Nostra, including racketeering, illegal waste dumping, money laundering and drug trafficking.
