World leaders and politicians around the globe expressed their support Sunday for families and victims of the deadliest U.S. mass shooting in modern history.
Earlier that day, suspected attacker Omar Mateen killed at least 50 people and wounded dozens more at a gay nightclub in Orlando, Florida. Authorities are investigating the killings as an act of terror, as information continues to emerge on the attack.
Many of the leaders offering solidarity following the shooting in Orlando are from countries, such as France and Belgium, that have suffered their own horrific attacks recently.
Belgian Prime Minister Charles Michel was one of the first leaders to send out condolences on Twitter, saying he was "deeply saddened." In March, the self-described Islamic State group claimed a terror attack in Belgium's capital of Brussels that killed 32 people.
A number of members of Britain's government, including Prime Minister David Cameron and London Mayor Sadiq Khan, tweeted out their support on Sunday. Khan, the city's first Muslim mayor, added the pro-LGBT rights hashtag "#lovewins" to his message of solidarity.
French President Francois Hollande, Paris Mayor Anne Hidalgo and the official city of Paris Twitter account all voiced their support and sympathies for those affected by the killings in Orlando. An ISIS terror attack in Paris last November that targeted a number of locations, including the Bataclan concert hall, killed 130 people and injured hundreds.
"On behalf of Parisians, all our deepest solidarity with the American people after the horrible attack in Orlando."
"I condemn with horror the killing that has caused at least 50 dead in Florida. I express France’s full support to the American people."
Norwegian Prime Minister Erna Solberg and Foreign Affairs Minister Borge Brende both sent out their condolences to the victims and families following the attack. Norway suffered a horrific mass shooting in 2011, when anti-Muslim terrorist Anders Behring Breivik killed 69 people -- the majority of them teenagers -- on the tiny island of Utoya.
Israeli President Reuven Rivlin called the attack "cowardly" on Twitter, and said his country stands with the United States. A terror attack in Tel Aviv, Israel, last week killed four people at a popular market, and wounded more than a dozen.
The official Twitter account of Tel Aviv also tweeted out a message of solidarity with Orlando and the LGBT community, showing Tel Aviv City Hall lit up in rainbow colors.
Afghan President Ashraf Ghani condemned the attack, saying that nothing justifies the murder of civilians.
Ban Ki-moon, secretary general of the United Nations, also condemned the attack and stood by victims, according to the U.N.'s official Twitter account.
Mexico's President Enrique Pena Nieto expressed solidarity with the families and condemned the violence in Florida.
"Mexico deeply laments the acts of violence in Florida and expresses its solidarity with the affected families and the American people."
