  We'll be back again early tomorrow with COVID-related news on Melbourne Cup Day. If you're celebrating with loved ones please stay safe and enjoy the day.

"Police will not allow anyone to engage in criminal or disruptive behaviour, particularly those that have a negative impact on the rest of the community."

Despite restrictions being relaxed, anti-lockdown groups are still planning to gather in the CBD on Cup Day at midday for the second time this long weekend.

On Saturday 21 people were arrested at protest in Treasury Gardens, with more than 100 officers swarming the planned event.

Of the 21 arrested, 20 were fined for breaching Chief Health Officer directions (worth $1652 per fine) while the other person was arrested for a drug-related offence.

"Everyone has a right to protest peacefully, as long as it is in accordance with the Chief Health Officer directions and does not impact the rest of the community, who also have the right to go about their daily business," the police spokeswoman said.

"Anyone coming into the city in blatant breach of the directions, or looking to disrupt others, create conflict and incite violence can expect a very firm response from police."

Sergio Mattarella, the president, called for national unity during a visit to a cemetery on Sunday in northern Italy, where thieves recently stole a large bronze cross erected in memory of COVID-19 victims. While Prime Minister Giuseppe Conte has repeatedly ruled out a second nationwide lockdown, he is under pressure to take more drastic action as infection rates continue to rise sharply.

On Sunday, Italy registered 29,907 new infections, with 208 deaths. There was particular concern for the city of Milan, which recorded 8047 positive cases in the last week of October, compared with 787 per week at the start of the month.

Tensions are running high within the governing coalition about whether to continue face-to-face schooling, and how to reduce crowding on public transport and bottlenecks in the testing system.

The popularity of the area carried on into Sunday, helped perhaps by the sunny weather and the fact that the Cup Day long weekend would provide many Melburnians with more time to sleep off a big meal.

More people flocked to Lygon Street at lunchtime on Sunday than on Saturday, and the pedestrian volumes were far higher than a typical Sunday night.

There were 61 asymptomatic infections reported on Saturday.

The new cases emerged after China tested millions of people across the region last week. Some of the asymptomatic infections were found in a county near the outbreak's original epicentre in Kashgar prefecture, raising fears that the virus is spreading.

The outbreak is China's worst since a June-July surge in Beijing saw more than 330 cases in less than a month. While Xinjiang's outbreak is so far smaller than the one that hit the Chinese capital, the detection of dozens of asymptomatic cases underscores the difficulty of stamping out the virus even with some of the world's most aggressive testing and contact tracing measures.

Roughly the size of Alaska, Xinjiang has a population of 22 million, or around 1.5 per cent of the national total. Beijing, whose rights record in the province has drawn global criticism, maintains that it's fighting separatism and religious extremism among Uighurs – and has made the region one of China's most-surveilled.

Gu Yingsu, deputy director of Xinjiang's health commission, said at a press conference Saturday that the second round of testing had been completed and that all those found to have COVID-19 were in quarantine.
