In France, police have arrested two more people who want to be heard about the Nice knife attack, sources told the news agency AFP.

Authorities now have a total of five people in their hotels whose connections to the Tunisian-backed attacker are being investigated.

Of the last two arrests, one is 25 years old and the other 63 years old, the legal source says.

They were arrested on Saturday.

Three people were killed on Thursday and several were wounded in a knife strike at a church in Nizala early in the morning.

The act is being investigated as a terrorist act.

An attacker with a Tunisian background was wounded during the arrest.

The attacker's condition in the hospital is serious and authorities have not been able to interrogate him.

The situation in France is tense

In France, the situation has been very tense since the re-publication of caricatures of the Prophet Muhammad by the satirical newspaper Charlie Hebdo.

The situation has intensified further since last month, when the trial related to the 2015 delivery attack began.

A few weeks ago, a radicalized man killed history teacher Samuel Paty.

The teacher was brutally killed near Paris by cutting his neck.

The act is suspected of an 18-year-old Chechen man who died in police bullets.

Paty was killed after showing students cartoons of the Prophet Muhammad as he dealt with freedom of speech.

An Orthodox priest was shot in France yesterday afternoon.

Lyon prosecutor Nicolas Jacquet has said an arrest related to the shooting case was made on Saturday night.

The prosecutor said the arrested person may be responsible for matching the eyewitness description of the suspect.

At the time of his arrest, he had no weapon with him.

There is no information about the motive for the act.

Protests against France and Macron

Opposition to France and President Emmanuel Macron has been demonstrated around the world, and a boycott of French products has been called for after Charlie Hebdo republished the caricatures.

Macron has repeatedly said that France will not bend.

However, in an interview with al-Jazeera on news channel Saturday, Macron had softened his voice.

The president said he understood that caricatures could be a shock to some people.

He stressed that violence is never justified and that he believes that freedoms and rights must be protected.
