Croatian Prime Minister Andrej Plenkovic on Friday condemned in the strongest terms Thursday's knife attack inside a church in the southern French city of Nice and expressed full support to France in its fight against terrorism.

“Croatia condemns the Nice attack in the strongest terms, and sees that as an attack against our values,” the Croatian premier writes this message in the French language on his Twitter account.

He writes that Croatia expresses solidarity with France and the French in this distressing period.

Plenkovic says he supports President Emmanuel Macron and the French government in their struggle against terrorism.

During the deadly attack, a lone attacker armed with a knife entered the Notre Dame Basilica in Nice at around 9am Thursday and shouted “Allahu Akbar”, according to news reports. A man and a woman died at the scene, while another woman died from her injuries. The attacker was injured after being shot by police and taken to hospital.

A few hours later, a man was shot dead near the southern French city of Avignon, after reportedly threatening police with a handgun, and according to news reports, a guard outside the French consulate in Jeddah, Saudi Arabia, was attacked and wounded.

Those attacks ensued in the wake of the killing of school teacher Samuel Paty by an 18-year-old Islamist.
