The suspected double murder occurred outside the Jewish Museum in Washington DC late on Wednesday, local time. The suspected shooter shouted "free Palestine" when he was arrested shortly after.
He is being investigated by the FBI and on Thursday, he was suspected of murder, murder of foreign officials, and weapons offenses.
I did it for Palestine, I did it for Gaza, he is said to have told the police, according to AP.
"Incitement" rejected
Israel's Foreign Minister Gideon Saar believes there is a "direct link" between the murders and "anti-Semitic and anti-Israeli incitement".
This incitement is made by leaders and officials in many countries and international organizations, especially from Europe, he says at a press conference.
Prime Minister Benjamin Netanyahu describes the incident as "the terrible price of anti-Semitism and the wild incitement against Israel" in a statement.
France rejects the claims of incitement. Christophe Lemoine, spokesperson for the French Foreign Ministry, calls it "completely unjustified statements".
France has condemned, France condemns and France will continue to condemn, always and unequivocally, all anti-Semitic actions, he says, according to AFP.
Last week, a large number of European countries criticized and condemned Israel's blockade of humanitarian aid to Gaza and Israeli statements about taking over the entire war-torn area.
The victims: Young couple
The shooting was caught on surveillance cameras, according to AP. The suspected perpetrator was seen walking back and forth outside the Jewish Museum before approaching four people and opening fire on a man and a woman.
He is said to have shot several times even after the victims fell to the ground.
The shooter then entered the museum where he was arrested by security guards. The suspect is from Chicago and not previously known to the police, according to NPR.
The murder victims had participated in a Jewish event at the museum, among other things, for diplomats.
Israel's ambassador to the US, Yechiel Leiter, describes the victims as a young couple.
US President Donald Trump calls the act "obviously anti-Semitic" on his platform Truth Social and emphasizes that hate and radicalization do not belong in the US.
Israel's UN ambassador Danny Danon describes it as "a depraved anti-Semitic act" on X.
