Spain declared a national state of emergency Sunday to tackle a second coronavirus wave as the World Health Organization (WHO) reported a third straight day of record new infections around the world.

France set a daily record of more than 50,000 COVID-19 cases.

In the US, which has the world's worst toll at around 225,000 deaths, challenger Joe Biden accused President Donald Trump's administration of waving "the white flag of defeat" after his chief of staff Mark Meadows said: "We are not going to control the pandemic."

The WHO has warned that some countries are on a "dangerous track," with too many witnessing an exponential increase in cases, and called on authorities to take decisive action to curb the spread of the disease.

The UN agency's figures showed that 404,793 cases were declared on Sunday alone, half of them in Europe, which it said that it was at an especially critical juncture with winter looming.

COVID-19 has now claimed the lives of 1.1 million people and infected more than 42 million globally.

WHO head Tedros Adhanom Ghebreyesus called for global solidarity in a future rollout of any vaccine, warning that "vaccine nationalism will prolong the pandemic, not shorten it."

As the disease continued its relentless march across Europe, Spanish Prime Minister Pedro Sanchez announced the new state of emergency and overnight curfews across the entire country except for the Canary Islands.

Spain was the first EU member state to pass the bleak milestone of 1 million cases and has been joined since by northern neighbor France.

"The situation we are going through is extreme," Sanchez said.

Italy - the epicenter of the first European outbreak - also ramped up restrictions on daily life, ordering the closure of theaters, cinemas and gyms and shutting bars and restaurants early.

Governments are struggling to balance new restrictions against the need to revive economies already battered by earlier draconian lockdowns after the virus first emerged in late 2019.

But populations weary of social isolation and economic hardship have bristled at the tougher measures.

"This is going to destroy us," Augusto D'Alfonsi, who owns the Torricella family-run fish restaurant in Rome, told AFP after the new measures were announced.

Dozens of far-right protesters in Rome clashed with riot police overnight during a demonstration against a curfew, setting off fireworks, burning bins and throwing projectiles.

Police in Berlin also broke up a protest against curbs, and launched an arson investigation after an attack on a building that housed the public health agency.
