Thousands of protesters in Hong Kong marched to the US Consulate today to drum up international support, calling on President Donald Trump to liberate the city as street fires started by demonstrators raged on.

Police stood by as anti-government activists waved Stars and Stripes flags and placards appealing for help and democracy on Sunday, following another night of violence in the 14th week of unrest.

The city turned to chaos over the weekend with lasers being used to confuse police who fought back with painful tear gas to disperse crowds, windows being smashed and street fires being started.

US Defense Secretary Mark Esper on Saturday urged the Chinese government to exercise restraint in Hong Kong.

Esper made his call in Paris as police in Hong Kong prevented protesters from blocking access to the airport during a security blitz but resisted protesters for a second night running in the densely populated district of Mong Kok.

President Donald Trump, however, has indicated that the US would stay out of a matter he considers to be between Hong Kong and China. He has said he believes the US trade war with China is making Beijing tread carefully.

Hong Kong has been rocked by a summer of unrest kicked off by a proposed law that would have allowed criminal suspects to be sent to mainland China for trial.

Many saw the extradition Bill as a glaring example of the Chinese territory's eroding autonomy since the former British colony was returned to China in 1997.

Hong Kong's leader Carrie Lam promised last week to withdraw the Bill - an early demand of protesters - but that has failed to appease the demonstrators, who have widened their demands to include other issues, such as greater democracy.

On Sunday, protesters donned 'Make Hong Kong Great Again' hats and filed past Washington's consulate singing the US national anthem as they called on the country to pressure Beijing to meet their demands and for Congress to pass a recently proposed bill that expresses support for the movement.

'More than 1,000 protesters have been arrested. We can't do anything but come out onto the streets, I feel hopeless,' 30-year-old protester Jenny Chan, told AFP.

'I think aside from foreign countries, no one can really help us,' she added.

On Saturday, Hong Kong turned to chaos as bonfires and debris lined the streets, with dozens of activists needing urgent first aid after being hit by clouds of painful tear gas.

Handheld lasers, which emit powerful beams of green and blue light, were used by pro-democracy activists to daze officers and scramble face recognition cameras.

Earlier in the day police stopped the planned disruption at the airport with a security blitz that included checking passengers on trains and buses heading to the airport and limiting train services.

Hong Kong's airport, the world's eighth busiest, has been a frequent target during the protests. Airport operations ran normally on Saturday following the security operation.

Protesters staged rallies at subway stations and malls on Saturday evening owned by the rail link operator MTR, accusing it of helping police during a recent violent raid at one station.

The Prince Edward station was shut for a second day on Saturday after protesters started gathering, laying white flowers and burning paper offerings at the station's exit as a sign of mourning.

When protesters refused to disperse and began setting fire to debris near the station, riot police chased them and used pepper spray.

Hong Kong has been rocked by a series of anti-government protests for the past three months. The demonstrations were initially sparked by a proposed law that would allow some criminal suspects to be sent to the mainland China to stand trial

The station has been a focus this past week for protesters, who want the rail operator to release security camera footage to substantiate rumours that some people died during the police.

Police have reiterated that there have been no deaths since the protests began in early June and condemned the online rumours as malicious.

Violent clashes separately took place at a station in Sha Tin new town, where protesters chased police officers into the control room before riot police arrived. Several people were detained.

Over the weekend, German Chancellor Angela Merkel renewed her pleas for a peaceful solution to the political turmoil during her trip to Beijing, calling for the 'violence' not to end in 'catastrophe'.

Her trip to Beijing, to strengthen ties between German and Chinese markets, has been overshadowed by the protests in Hong Kong.

The former British colony of Hong Kong returned to China in 1997 under a 'one country, two systems' formula that guarantees freedoms not enjoyed on the mainland. Many Hong Kong residents fear Beijing is eroding that autonomy.

China denies the accusation of meddling and says Hong Kong is an internal affair. It has denounced the protests, accusing the United States and Britain of fomenting unrest, and warned of the damage to the economy.

The persistent violence has hurt Hong Kong's economy and sparked fears of a Chinese military intervention. Chinese officials have warned that Beijing will 'not sit idly by' if the situation worsens.

Protesters have adopted a new slogan, 'Five key demands, not one less.' In addition to the withdrawal of the extradition bill, they want an independent investigation into accusations of police brutality, the unconditional release of those detained during the protests, no more labeling of the protests as riots and direct elections of the city's leaders.

Lam has rejected those demands.

The protests show no signs of abating ahead of China's National Day celebrations on October 1, despite Lam's concession on the extradition bill.

The increased scrutiny was aimed at avoiding the chaos of last weekend, when protesters blocked airport approach roads, threw debris onto train tracks and subway stations in a 'stress test' protest. Above: Riot police advance during a protest near Mong Kok police station in Hong Kong on Saturday
