Italy's prime minister sends message of condolence after Manchester terror attack.

Italian prime minister Paolo Gentiloni has sent condolences to Manchester following the terror attack that killed at least 22 people and injured about 60, many of them minors, at an Ariana Grande concert on the evening of 22 May.

Rome's mayor Virginia Raggi has also sent her condolences via Twitter. She tweeted: "Rome stands with #Manchester. Our thoughts go out to all those affected by yesterday's tragedy."

The US president, Donald Trump, and his entourage arrive in Rome on the evening of 23 May and Raggi has said that the capital is working closely with the country's security chiefs to “keep the city safe” during their time in Rome.

Major security measures are also in place in Taormina in Sicily where Trump will attend the G7 conference on 26 May.

Italy suspended Schengen rules for entry into the country several weeks ago and border checks have been strengthened.
