At least 53 people have died and dozens others have been injured after a strong earthquake in China, according to the country’s state media.

The 6.8 magnitude earthquake struck in a mountainous area in the autonomous Tibet region, near the border with Nepal, shortly after 9.05am on Tuesday, according to the China Earthquake Networks Centre.

The US Geological Survey (USGS) said it had recorded a 7.1 magnitude earthquake, centred in the Tibet region.

China’s state-run Xinhua News Agency, citing the regional disaster relief headquarters, said alongside the 53 people who had died, 62 others had been injured.

About 1,500 fire and rescue workers have been deployed to search for people in the rubble, China’s Ministry of Emergency Management said.

State broadcaster China Central Television (CCTV) said the epicentre was in the Tingri region, around 380 kilometres (240 miles) from Tibet’s capital Lhasa and about 23 kilometres (14 miles) from the region’s second-largest city of Shigatse – also known as Xigaze.

Shigatse is one of the holiest cities of Tibet. It is home to the Tashilhunpo Monastery – the traditional seat of the Panchen Lama, who is second only to the Dalai Lama in terms of spiritual authority in Tibetan Buddhism.

According to state media, the initial earthquake was followed by a number of aftershocks with magnitudes of up to 4.4. Tremors were also felt in Nepal’s capital, Kathmandu, as well as Bhutan and northern India.

Anoj Raj Ghimire, chief district officer of Solukhumbu district in Nepal, said: “We felt a very strong earthquake. So far we have not received any report of injuries or physical loss.”

The earthquake struck in an area where the Indian and Eurasian plates clash, causing uplifts which form the Himalayan mountains.

There have been 10 earthquakes of at least magnitude 6 in the area where Tuesday’s quake hit over the past century, the USGS said.

A 7.8 magnitude earthquake killed some 9,000 people and damaged about 1 million structures in Nepal in 2015.

Canadian Prime Minister Justin Trudeau has announced his resignation.

The 53-year-old said he will step down as leader of the country’s ruling Liberal Party, which he has led since 2013.

He says it will allow his party to choose a new leader as he suspends parliament until March due to political deadlock.

Speaking to reporters in front of his residence at Rideau Cottage, in the country’s capital, Ottawa, he said “internal battles” mean that he “cannot be the best option” in the next election.

“I don’t easily back down faced with a fight, especially a very important one for our party and the country. But I do this job because the interests of Canadians and the well-being of democracy is something that I hold dear.

“A new prime minister and leader of the Liberal Party will carry its values and ideals into that next election. I am excited to see that process unfold in the months ahead.”

Former governor of the Bank of England, Mark Carney, is among the favourites to succeed him.

Chrystia Freeland, whose stunning resignation as finance minister and deputy prime minister precipitated the current crisis, leads in the polls.

Other front-runners are the former premier of British Columbia, Christy Clark, current finance minister Dominic LeBlanc and minister of foreign affairs, Melanie Joly.

Mr Trudeau, who has been prime minister since 2015, faced calls to quit from a chorus of his MPs amid poor showings in opinion polls.

He came under further pressure after Ms Freeland quit in December because of policy disagreements, including over how to handle possible US tariffs imposed by Donald Trump‘s incoming administration.

Mr Trudeau’s resignation comes as the polls show his party is likely to suffer a heavy defeat to the official opposition Conservatives in an election that must be held by late October.

The Liberals must now name an interim leader to take over as prime minister ahead of a special leadership convention.

Mr Trudeau came to power 10 years ago following a decade of Conservative Party rule and was initially praised for returning the country to its liberal past.

But he has become deeply unpopular with voters in recent years over a range of issues, including the soaring cost of food and housing and surging immigration.

He is the eldest son of Pierre Trudeau, one of Canada’s most famous prime ministers, who led the country from 1968 to 1979 and from 1980 to 1984.

The political upheaval comes at a difficult moment for Canada internationally.

US President-elect Donald Trump has threatened to impose 25% tariffs on all Canadian goods if Ottawa does not stem what Mr Trump calls a flow of migrants and drugs into the US.

Many fewer of each cross into the US from Canada than from Mexico, which Mr Trump has also threatened.

In a social media post on Christmas Day, Mr Trump even suggested the US could take control of Canada, as well as Greenland and the Panama Canal.

Canada is a major exporter of oil and natural gas to the US, which also relies on its northern neighbour for steel, aluminium and autos.
