BARCELONA : Residents of Barcelona were urged to stay home and not gather in groups of more than 10 on Friday as regional authorities sought to curb a rise in coronavirus cases, while stopping short of imposing a mandatory lockdown."We recommend that people don't move around if it's not absolutely necessary," Catalonia's health chief Alba Verges told a news conference. "It is very important to respect these measures now, it's the best way to avoid a lockdown."Residents were urged to shop online and cultural and sports events will also be limited.
