Here's what we know about last night's terror attack in Manchester, England:
- What appears to have been a device detonated by suicide bomber exploded at 10:30 p.m. local time after an Ariana Grande concert in the 21,000-seat Manchester Arena.
- At least 22 people have died as a result of the blast. The youngest known victim was eight years old.
- ISIS has claimed responsibility for the attack, which is believed to have been perpetrated on site by a 22-year-old man named Salman Abedi who was born in Manchester to Libyan parents.
- A 23-year-old man who is believed to have a connection to the incident was arrested in Manchester on Tuesday morning.
- Donald Trump, speaking in the West Bank, called the perpetrators of the attack "evil losers."
The incident is the U.K.'s deadliest terror attack since the 2005 London transit bombings in which 52 were killed. It follows a number of other recent high-casualty attacks in Europe, including the January 15 Charlie Hebdo attacks in Paris; the November 2015 Bataclan attacks in Paris; the March 2016 bombings in Brussels; the July 2016 truck attack in Nice, France; and the December 2016 truck attack in Berlin.
