The terrorist who killed and injured some 100 worshippers at New Zealand mosques last week “will pay,” vowed Turkey’s president on Tuesday.

Axar.az reports citing Anadolu News Agency.

"You will pay for this. If New Zealand doesn't do so, one way or another we will make you pay," Recep Tayyip Erdogan said of the terrorist, speaking at a campaign rally in Turkey’s Black Sea province of Zonguldak.

At least 50 people were killed and about as many injured when a terrorist opened fire on worshippers during Friday prayers at the Al Noor and Linwood mosques in Christchurch, New Zealand’s third-largest city.

The massacre was livestreamed on social media, and was accompanied by the release of a racist, Islamophobic, manifesto that also attacked Turkey.

Brenton Harrison Tarrant, a 28-year-old Australian, is being charged over the massacre.
