Celebrities like Kris Jenner have paid tribute to all the victims of the New Zealand shooting.

The mass shooting, which the country's prime minister described as a terror attack and "one of New Zealand's darkest days," left at least 49 people killed and 20 seriously injured after a man in his late 20s targeted two mosques in the city of Christchurch on Thursday (Mar. 14). The unidentified suspect was arrested and charged with murder after authorities found an "87-page manifesto filled with anti-immigrant, anti-Muslim ideas," according to CNN.

"My heart is with New Zealand this morning. Praying for the victims and their families," the Keeping Up with the Kardashians star wrote on Twitter alongside a heartbroken emoji.

Others Hollywood stars like John Legend called on Donald Trump to condemn white supremacy the U.S. and urged him to take "real steps" to combat it. He also tweeted, "The killings in New Zealand are so horrific and heartbreaking. This white supremacist terrorist movement is so destructive here and abroad. We need to unite against it."

Meanwhile, Mark Ruffalo, former president Barack Obama, and Melissa Joan Hart reacted to the devastating news with messages of support and disbelief. Check out all the celeb reactions below:
