In Rabat, demonstrators carrying Moroccan flags demanded "health and not just stadiums", according to an AFP journalist, who said there were no violent incidents.

Many feel that the public health and education sectors in Morocco should be improved as the kingdom pushes forward with major infrastructure projects to host the Africa Cup of Nations next month and the 2030 World Cup.

Other rallies were also reported on Thursday in Casablanca, Marrakech and Agadir, also with no sign of unrest.

The protests across the usually stable country have been fueled by anger over social inequality, particularly following reports last month of the deaths of eight pregnant women at a public hospital in Agadir.

The protests that erupted Saturday were called by the group GenZ 212 on the online messaging platform Discord, where it has now over 150,000 members.

But the group, whose organizers remain unknown, has repeatedly distanced itself from the violence and acts of vandalism that some cities have seen.

Earlier in the day, Prime Minister Aziz Akhannouch said in his first public address since the unrest started that his government was willing to "engage in dialogue" and "respond to the (protesters') demands".

The premier also said three people had been killed during protests the night before, describing the events as "regrettable". 

An interior ministry spokesman said that all three demonstrators were killed after attempting to storm a local law enforcement station Wednesday night.

The authorities had initially said two protesters were killed when officers opened fire on a group of demonstrators that they accused of wielding "bladed weapons" and said had attempted to "storm" the station near Agadir.

Deputy Minister of Solidarity Abdeljebbar Rachidi also said the government was willing to listen to the mainly young protesters.

And Health Minister Amine Tehraoui announced in a speech to parliament on Wednesday evening that several health reforms were underway but acknowledged that these endeavors were "still insufficient to close the sector's gaps".

Since the demonstrations started, hundreds of mostly young people have been arrested.

GenZ 212 has urged demonstrators not to turn to violence, announcing that Thursday's protests were going to be peaceful "as part of a civilized and responsible expression of our demands".

Still, Morocco's interior ministry has said that more than 400 people had been arrested during the rallies as of Wednesday night, with nearly 300 people -- mainly from security forces -- injured.

It also said 80 public and private establishments were vandalized, adding that demonstrators were behind "significant" material damage to 271 government vehicles and 175 privately owned cars.

Some 134 people, six of whom are in detention, are set to be tried in Rabat soon, according to lawyers.

Demonstrators have called for "the fall of corruption" as well as "freedom, dignity and social justice", while some urged Akhannouch to step down.

Despite its calls for protests, GenZ 212 has also asserted its "love for the homeland and king", referring to Morocco's monarch Mohammed VI.

It however says it stands against some political parties.

Clashes erupted in some cities, including in Sidi Bibi, near Agadir, where demonstrators set offices of the local commune headquarters on fire, according to media reports and videos on social media.

In the city of Sale, north of the capital Rabat, an AFP journalist saw hooded demonstrators set fire to two police cars and a bank branch.

"The young people I saw vandalizing and breaking things in Sale have nothing to do with GenZ 212," said Hicham Madani, a resident. "They are young thugs who came with the intention of vandalizing."

Ahead of Thursday's demonstrations, GenZ 212 said it "rejects all forms of violence, vandalism or rioting". 

It reminded protesters "to respect the peaceful nature" of the movement.
