Thousands of people took part in a silent march in Bayonne for Philippe Monguillot, 59, who was declared brain dead after an attack by passengers who refused to wear face masks.
French Interior Minister Gerald Darmanin is scheduled to travel to Bayonne on Saturday to meet Trambus drivers and discuss issues concerning security.

Mr Monguillot was attacked in the southwestern town of Bayonne on Sunday after he reportedly asked three passengers to wear masks - in line with coronavirus rules across France - and tried to check another man's ticket. The other two men have been charged with non-assistance to a person in danger and one has also been charged with attempting to hide a suspect, the local prosecutor's office said.
French Prime Minister Jean Castex said the incident "touches us in the heart" and those involved will be punished for this "abject crime", he wrote on Twitter shortly after his passing.

Monguillot was hospitalized and declared brain dead after the July 5 attack at a bus stop in Bayonne, in southwest France.
The Bayonne prosecutor said Monguillot was assaulted after he asked four passengers on his No. 810 bus to wear face masks, which are required aboard French public transport because of the coronavirus pandemic. "The doctors were in favour and we were as well", she told AFP. "We must stop this massacre".

He said: "This [the attack] was a totally odious and unjustifiable act and I trust the magistrate to work with investigators of the Bayonne police to do everything possible to deal with those who committed these barbaric acts".
