Following a dramatic penalty shootout, Morocco became the first Arab side to make it to the World Cup quarterfinals.
This is the second time Moroccan players have raised the Palestinian flag after winning a match. Morocco’s player Jawad El Yamiq raised the Palestinian flag while celebrating his country’s 2-1 victory over Canada last week.
Moroccan football fans were also seen waving a “Free Palestine” banner during the North African country’s 2-0 victory over Belgium in Group E earlier in the tournament.
Regulations from FIFA, soccer’s global governing body, prohibit the use of banners, flags and fliers that are deemed to be political, offensive and/or discriminatory in nature.
“The promotion or announcement of political or religious messages or any other political or religious actions, inside or in the immediate vicinity of the stadium, by any means, is strictly prohibited before, during and after matches,” FIFA regulations state.
Football authorities have occasionally issued fines for displays of the Palestinian flag inside grounds.
The flag bearing move was hailed by Arabs on social media, as users from Libya, Morroco, Egypt and Saudi Arabia celebrated the Moroccan win.
Videos on social media also show Palestinians celebrating Morocco’s win in the streets of several cities in the West Bank and in Gaza.
CNN has reached out to FIFA for comment.
