New Zealand authorities announced that four people including one Australian had been detained in connection with the shooting, which the country's prime minister called an act of right-wing terrorism.

One man who claimed to have perpetrated the attack left a more than 70-page anti-immigrant manifesto in which he explained his reasoning. Videos and photos on his social media page that appeared to have been taken live during the attack were shared on the platforms before being taken down.

In the online manifesto, the suspect declared himself to be a 28-year-old Australian radicalized online by right-wing influencers amid pages of rhetoric against Muslims and other minorities.

Omar herself has been at the center of controversy in recent weeks over statements about the U.S. relationship with Israel, with some accusing her of making anti-Semitic comments and others defending her and accusing her detractors of targeting the Muslim congresswoman over her own faith.

A former refugee from Somalia, Omar has been critical of the Israeli government and its support in the U.S. and came under fire after tweeting that such support was "all about the Benjamins," a reference to a 1990s song by P. Diddy that some said also referenced an anti-Semitic trope.

She was also criticized for suggesting that she was being forced to declare "loyalty" to Israel in order to serve on the House Foreign Affairs Committee during an exchange with Rep.
