The world hailed Chinese Nobel peace laureate Liu Xiaobo as a brave fighter for human rights after his death from cancer.
Liu, a government critic and thorn in the side of the authorities for decades, died in custody, having been sentenced to 11 years in prison in 2009 for "subversion".
His death brought criticism for Chinese authorities who refused international pleas to let him receive treatment abroad.

"We find it deeply disturbing that Liu Xiaobo was not transferred to a facility where he could receive adequate medical treatment before he became terminally ill," Berit Reiss-Andersen, who chairs the Norwegian Nobel Committee, said in a statement.
"The Chinese government bears a heavy responsibility for his premature death."
- United States -
US President Donald Trump initially refrained from commenting on Liu's death and avoided criticising Beijing at a joint press conference in Paris with French leader Emmanuel Macron.
He instead used the occasion to praise China's leader Xi Jinping as a friend and patriot.
Several hours later, the White House released a statement about Liu.
"President Donald J. Trump was deeply saddened to learn of the passing of Nobel Peace Prize laureate and prominent Chinese political prisoner Liu Xiaobo," it said.
"The president's heartfelt condolences go out to Liu Xiaobo's wife, Liu Xia, and his family and friends. A poet, scholar, and courageous advocate, Liu Xiaobo dedicated his life to the pursuit of democracy and liberty."
Earlier, Trump's Secretary of State Rex Tillerson had praised Liu and called for his widow, the poet Liu Xia, to be released from house arrest.
And the US ambassador to the United Nations, Nikki Haley, called Liu "a true champion for freedom and an inspiration to those longing for democracy around the world."

"I mourn Liu Xiaobo, the courageous fighter for human rights and freedom of expression," German Chancellor Angela Merkel's spokesman Steffen Seibert tweeted on her behalf.
"His family has my deep sympathies."
Germany had said it was prepared to welcome Liu for medical treatment after he was transferred from prison to hospital.
- United Nations -
"The human rights movement in China and across the world has lost a principled champion who devoted his life to defending and promoting human rights, peacefully and consistently, and who was jailed for standing up for his beliefs," the UN High Commissioner for Human Rights, Zeid Ra'ad Al Hussein, said in a statement.
"Liu Xiaobo was the true embodiment of the democratic, non-violent ideals he so ardently advocated."
- European Union -
European Commission chief Jean-Claude Juncker and EU president Donald Tusk said in a joint statement that they had learned of Liu's death "with deep sadness".
"We appeal to the Chinese authorities to allow his wife, Ms Liu Xia and his family to bury Liu Xiaobo at a place and in a manner of their choosing, and to allow them to grieve in peace," Juncker and Tusk said.
"We call on the authorities to remove all restrictions on the movement and communications of his family members."
- France -
Like Trump, French President Emmanuel Macron also initially avoided discussing Liu's death, focusing instead on his "extremely fruitful and positive" contacts with Xi.
The French leader later remembered Liu in a tweet, praising him as "a freedom fighter" and saying his thoughts were with his family.
- Britain -
British Foreign Minister Boris Johnson hit out at China for preventing Liu from seeking cancer treatment abroad.
"Liu Xiaobo should have been allowed to choose his own medical treatment overseas, which the Chinese authorities repeatedly denied him," Johnson said in a statement.

Chen Guangcheng, one of China's best-known activists who fled to the United States in 2012, said Liu was "deliberately killed" by the country's rulers and urged the international community to maintain pressure on Beijing.
"We need to see his death as not a natural, normal death," Chen told AFP in a telephone interview from Washington.
"He was killed by the CCP (Chinese Communist Party), deliberately killed by them."
Chen said China had refused to allow Liu to travel abroad for treatment because they "were likely to discover what was really wrong with him and would probably reveal that they had been harming him with medication or some such things."
"As a vocal outspoken Nobel prize winner, he would likely speak out about what has happened to him, and that's another thing that the Chinese Communist Party did not want to have happen," Chen added.
