President Recep Tayyip Erdogan of Turkey has rallied Turks to boycott French goods amid a row over France's tougher stance on radical Islam.

In a televised speech, he urged world leaders to protect Muslims "if there is oppression against Muslims in France".

Mr Erdogan has angrily criticized French President Emmanuel Macron for pledging to defend secularism against radical Islam.

It comes after a teacher was killed for showing Prophet Muhammad cartoons.

Samuel Paty was beheaded on 16 October by 18-year-old Abdullakh Anzorov outside Paris. France "will not give up our cartoons", President Macron said earlier this week.

Depictions of the Prophet Muhammad are widely regarded as taboo in Islam, and are offensive to many Muslims.

But state secularism - or laïcité - is central to France's national identity. Curbing freedom of expression to protect the feelings of one particular community undermines unity, the state says.

According to BBC, Mr Erdogan called for the boycott in a televised speech on Monday.

"Never give credit to French-labelled goods, don't buy them," he said in the capital Ankara.

He said Muslims are now "subjected to a lynch campaign similar to that against Jews in Europe before World War II", adding that "European leaders should tell the French president to stop his hate campaign".

Over the weekend, he said that Macron needed a mental health check for speaking out so forcefully on Islam - comments that caused France to recall its ambassador to Turkey for consultations.

It came after Mr Macron pledged to defend secularism and tackle radical Islam in the wake of the killing of Mr Paty.
