AMSTERDAM (REUTERS) - Thousands of protesters packed Amsterdam's streets on Sunday (Jan 16) to oppose government-imposed Covid-19 measures and vaccination campaign as virus infections hit a new record.

The authorities were granted stop-and-search powers at several locations across the city, and scores of riot police vans patrolled neighbourhoods where demonstrators marched with banners and yellow umbrellas.

Regular anti-coronavirus protests are held across the country and Sunday's large gathering was joined by farmers who drove to the capital and parked tractors along the central Museum Square.

The crowd played music, chanted anti-government slogans and then marched along thoroughfares, blocking traffic.

The Netherlands had one of Europe's toughest lockdowns for a month through the end-of-year holidays.

Amid growing public opposition, Prime Minister Mark Rutte on Friday announced the reopening of stores, hairdressing salons and gyms, partially lifting a lockdown despite record numbers of new Covid-19 cases.

Infections reached another record high of over 36,000 on Sunday, data published by the Netherlands Institute for Health (RIVM) showed. The Netherlands has recorded more than 3.5 million infections and 21,000 deaths since the start of the pandemic.

Mr Rutte's government ordered the lockdown in mid-December as a wave of the Delta variant forced the health system to cancel all but the most urgent care and it appeared rising Omicron cases would overwhelm it.

Non-essential stores, hairdressing and beauty salons and other service providers were allowed to reopen on Saturday under strict conditions.

Bars, restaurants and cultural venues have been instructed to remain closed until at least Jan 25 due to uncertainty over how the Omicron wave will impact hospital capacity.
