Rome, May 23 (IANS/AKI): Italian politicians on Tuesday tweeted solidarity with Britain over the suicide bombing at a concert venue in the northern city of Manchester that killed 22 people including children and injured around 60.

"Italy is close to the British people and government. Our thoughts go to the victims of the #Manchester attack and their families," wrote Italian Premier Paolo Gentiloni.

The blast happened in the foyer of the Manchester Arena late on Monday at the end of a concert by US singer Ariana Grande.

The lone male attacker, who died in the blast, detonated a homemade bomb, according to police.

"We are in mourning and pain over what happened in #Manchester. We are close to the British people and their government, as well as the injured and the victims' families," tweeted Foreign Minister Angelino Alfano.

Italy's ruling centre-left Democratic Party chief Matteo Renzi called the Manchester attack "heartbreaking".

"Death was sown at a concert attended by very young people, where music should reign. What happened in Manchester is heart-breaking. 

"Thoughts and prayers for the victims and their parents, for those families devastated by pain that began today and will never end," he said in a series of tweets.

Rome's grassroots Mayor Virginia Raggi tweeted directly in English: "Rome stands with #Manchester. Our thoughts go out to all those affected by yesterday's tragedy." 

World leaders, including US President Donald Trump, French President Emmanuel Macron, and Palestinian Authority President Mahmoud Abbas, have expressed outrage and condolences with Britain over the attack.
