RABAT, Morocco (AP) — Demonstrations have been staged in cities across Morocco against a coronavirus vaccine passport required to access indoor activities and travel. Proof of vaccination has been mandatory since Oct. 21 for all Moroccans to enter their place of work and restaurants and for domestic and international air travel. The North African kingdom’s vaccination rate is the highest in the continent, with more than 58% of its 36 million people fully inoculated. But a vocal minority is opposed. Protests were held Sunday in the capital of Rabat, Casablanca, Tangiers in the north and Agadir in the south.
