China extends Shanghai coronavirus lockdown as frustration mounts over strict "zero-COVID" policy

While most American cities are opening up and lifting COVID-19 restrictions, one of the biggest cities in the world has been shut back down. Shanghai, China's most populous city with some 25 million inhabitants, was largely at a standstill on Friday as China battles its worst wave of coronavirus infections since the start of the pandemic.

CBS News' Lucy Craft reports the hardships of the lockdown have raised questions about the Chinese government's adherence to its hardline "zero-COVID" strategy.

Shanghai's lockdown was supposed to last just a handful of days for residents, depending on where they lived, with a two-phase roll-out. The first half of the city — the Pudong district — went under restrictions on Monday, and it was meant to last there for five days before being lifted and transferred to the Puxi district for four days.
