The highest authority on Islam in Singapore, Mufti Nazirudin Mohd Nasir, has condemned the recent murders in the French cities of Paris and Nice.

"Once again, radical elements and extremists have committed heinous crimes on innocent individuals and in the most sacred of places," he said in a letter to leaders of Singapore's Christian community yesterday.

"Such attacks are not only an affront to the sacredness of the human soul, but also an assault on Islam, as they took place in the month where Muslims commemorate the birth of Prophet Muhammad by honouring him with good deeds and behaviour.

"These terrorists may have sought to exploit our love for the Prophet to gain sympathy, but their actions are a clear desecration of his teachings and have no place whatsoever in Islam or in any religion."

On Oct 16, 47-year-old history teacher Samuel Paty was beheaded by 18-year-old Abdullakh Anzorov in Paris. The attacker, who was later shot dead by the police, had said he wanted to punish Mr Paty for showing students cartoons of the Prophet in a civics lesson.

On Thursday, a knife-wielding Tunisian man, believed to be a Muslim, beheaded a woman and killed two others in a church in Nice before being caught by the police.

Yesterday, Dr Nazirudin said it is important that Singapore society remains committed to shared values and to ensuring that peace and harmony prevail.

He also said the Muslim community here will continue to work tirelessly with the Christian community to affirm their commitment to "the bonds of faith and friendship".

"We are confident that by strengthening the trust and confidence in each other, we will be able to prevent such incidents from ever taking place here," he said.

"We offer our sincerest prayers and solidarity to those whose lives were taken unjustly, to those who were injured and to their loved ones."

In a Facebook post yesterday, Minister of State for Home Affairs and National Development Muhammad Faishal Ibrahim also condemned the attacks, saying they "have no place in Islam".

He added that all Singaporeans must "stand united and firmly" against any form of extremist violence and hate speech. "This is how we can continue to maintain a strong and cohesive society."
