Shanghai has reported the first Covid-19 deaths since the start of its weeks-long lockdown, three elderly people with underlying conditions, the city government said.

“The three people deteriorated into severe cases after going into hospital, and died after all efforts to revive them proved ineffective,” the city said on social media, reports Reuters.

The deceased included two women aged 89 and 91, and a man aged 91, the city said, adding that they all had a variety of underlying health complaints such as coronary heart disease, diabetes and high blood pressure.
