Hundreds of people took to the streets in Beijing and Shanghai on Sunday to protest against China's zero-Covid policy in a rare outpouring of public anger against the state.

Residents of some parts of China's capital were emptying supermarket shelves and overwhelming delivery apps Friday as the city government ordered faster construction of COVID-19 quarantine centers and field hospitals.

Uncertainty and scattered, unconfirmed reports of lockdowns in at least some Beijing districts have fueled demand for food and other supplies, something not seen in the city for months.

Pandemic lockdowns are expanding across China, including in a city where factory workers clashed this week with police, as the number of COVID-19 cases hits a daily record.

Residents of eight districts of Zhengzhou, home to 6.6 million people, were told to stay home for five days beginning Thursday except to buy food or get medical treatment. Daily mass testing was ordered in what the city government called a "war of annihilation" against the virus.

The southern Chinese metropolis of Guangzhou locked down its largest district Monday as it tries to tamp down a major COVID-19 outbreak, suspending public transit and requiring residents to present a negative test if they want to leave their homes.

The outbreak is testing China's attempt to bring a more targeted approach to its zero-COVID policies while facing multiple outbreaks driven by fast-spreading omicron variants. China is the only major country in the world still trying to curb virus transmissions through strict lockdown measures and mass testing.

In response to the cholera outbreak in Lebanon, the EU is allocating €800,000 towards community-based water, sanitation and hygiene interventions in areas with a concentration of cholera cases, the EU Delegation to Lebanon said.

"Ongoing EU humanitarian programs are also redirecting efforts to address this new emergency," the Delegation added in a statement.

Human Rights Watch Monday accused the government in Damascus and Turkey of exacerbating Syria's deadly cholera outbreak by restricting aid and water-flow to the country's Kurdish-held northeast.
