RABAT: Workers in Morocco's vital tourism sector protested for the second time this month on Wednesday to denounce a two-month-old border closure aimed at countering the Omicron variant of coronavirus. Nearly 200 travel industry workers gathered in front of the tourism ministry in Rabat, while local media said other demonstrations occurred in the tourist centers of Agadir and Marrakesh. The North African country suspended all passenger flights from November 29 until at least January 31 as the highly infectious Omicron variant spread worldwide.
