Three man have been arrested in connection with the Monday terrorist attack in Manchester that killed 22 people and injured 59.

The men were arrested in South Manchester. Another man was also arrested in connection with the attack. The four are now being held by the British police.

Ever since the bombing, there has been considerable police activity around the area, with military personnel and police being deployed to protect key areas.

Many of the victims of the suicide attack were children, who were at the Manchester Arena during a concert by pop star Ariana Grande.

ISIS has claimed responsibility for the attack.

The man who carried out the bombing has been named as Salman Abedi, 22.

He was a British-born man of Libyan descent who was part of a wider network of ISIS terrorist group, including a bomb-maker who may still be free.

Following the Monday attack, ISIS supporters took to social media to celebrate the attack using hashtags that referred to the incident to post their celebratory messages.

Some users also encouraged similar attacks on other regions. They described the attack as an act of revenge for Western countries’ air strikes in Iraq and Syria.

The attack is the deadliest terrorist attack on Britain since July 2005 when 52 people were killed in a blast targeting London’s transport system.
