New Zealand’s largest online auction site is suspending sales of semiautomatic weapons after the deadly attack on two Christchurch mosques last week that killed 50 people.

Following an outcry from the mass shooting, the site TradeMe said it would also cease listing parts for the guns on Monday.

“We have listened to public sentiment following Friday’s terrorist attack in Christchurch and decided to remove all semi-automatic firearms sales and parts associated with those weapons,” CEO Jon Macdonald said in a statement. The sales will be stopped while “we wait for more clarity from the government,” he said.

“We’re obviously still reeling, like all New Zealanders, and our hearts go out to the victims and their families and friends.”

Organizers of New Zealand’s largest gun show, which had been planned for next week, canceled the event out of respect for the mosque victims and because of “elevated security risks,” The Associated Press reported.

The suspected gunman in Friday’s attack had five guns: two semiautomatic rifles, two shotguns and a lever-action firearm, The Wall Street Journal reported. He held a basic Category A New Zealand gun license, and likely legally purchased the weapons. Police believe he illegally modified an AR-15 with a large magazine.

Prime Minister Jacinda Ardern has said she will announce gun law reforms within 10 days.
