China has sent more than 10,000 health workers from around the country to Shanghai, including 2,000 from the military, as it struggles to stamp out a rapidly spreading outbreak in its largest city under its zero-COVID strategy.

Shanghai was conducting a mass testing of its 25 million residents Monday as what was announced as a two-phase lockdown entered its second week. Most of eastern Shanghai, which was supposed to re-open last Friday, remained locked down along with the western half of the city.

Ice-coated vines stretched across hillsides around Chablis as the Burgundy region woke Monday to temperatures of minus 5 C (23 F). Fruit growers are worried that the frost will kill off large numbers of early buds, which appeared in March as temperatures rose above 20 C (68 F), and disrupt the whole growing season.

Hong Kong leader Carrie Lam said Monday she wouldn't seek a second term after a rocky five years marked by huge protests calling for her resignation, a security crackdown that has quashed dissent and most recently a COVID-19 wave that overwhelmed the health system.

Her successor will be picked in May, with the city's hardline security chief during the 2019 protests seen as a likely choice.

Syrian government forces on Monday shelled a rebel-held village in northwestern Syria, the country's last major opposition stronghold, killing four students on their way to school, opposition activists said.

The shelling targeted the village of Maaret al-Naasan in Idlib province. The province is Syria's last major rebel stronghold and home to more than 3 million people, many of them internally displaced by the civil war that began in 2011.

The usual crowds filled the streets as bars and nightclubs were closing in California's capital city of Sacramento when the sound of rapid-fire gunshots sent people running in terror. In a matter of seconds, the latest U.S. mass shooting had left six people dead and 12 wounded.

Sacramento police said they were searching for at least two people who opened fire around 2 a.m. Sunday on the outskirts of the city's downtown entertainment district, anchored by the Golden One Arena that hosts concerts and the NBA's Sacramento Kings. The team's home game against the Golden State Warriors went on as scheduled Sunday night and began with a moment of silence for the victims.

With Pakistan in political turmoil, the country's Supreme Court is to convene Monday to hear arguments and later rule on whether Prime Minister Imran Khan and his allies had the legal right to dissolve parliament and set the stage for early elections.

The opposition is challenging the latest moves by Khan, a former cricket start turned conservative Islamist leader who came to power in 2018, as a ploy to stay on as prime minister. It has also accused him of economic mismanagement.

An outspoken half-brother of Jordan's king has relinquished his princely title in apparent protest over how the country is run. It was the latest chapter in an ongoing palace feud that saw the junior royal placed under house arrest a year ago.

A tanker carrying badly needed fuel arrived in Yemen's blockaded port of Hodeida on Sunday, as a cease-fire meant to stop the fighting in the war-torn country for two months entered its first full day.

The truce agreement, which took effect Saturday evening, allows for shipments of fuel to arrive in Hodeida and for passenger flights to resume from the airport in the capital of Sanaa. Both Hodeida and Sanaa are held by the Iranian-backed Houthi rebels.

Ukrainian troops moved cautiously to retake territory north of the country's capital on Saturday, using cables to pull the bodies of civilians off streets of one town out of fear that Russian forces may have left them booby-trapped.

Ukrainian President Volodymyr Zelenskyy warned that departing Russian troops were creating a "catastrophic" situation for civilians by leaving mines around homes, abandoned equipment and "even the bodies of those killed." His claims could not be independently verified.
