DUBAI (Reuters) - Bahrain’s government has crushed dissent and violently cracked down on protests in the past year, Amnesty International said on Thursday, and it accused Britain and the United States in particular of turning a blind eye to its abuses.

Amnesty said in a report on Thursday that it had documented how the Bahraini government, from June 2016 to June 2017, arrested, tortured, threatened or banned from travel at least 169 activists and opponents or their relatives.

Bahraini authorities could not immediately be reached for comment. Bahrain has repeatedly denied systematic rights abuses.

Entitled “No one can protect you: Bahrain’s year of crushing dissent”, the report said that at least six people were killed, including a child, in the crackdowns.

The report also accused Western governments, notably the United States and Britain of remaining silent. The two countries have a particularly high level of influence in Bahrain, where the U.S. Fifth Fleet is based and where Britain’s Royal Navy has a major facility.

Amnesty said U.S. President Donald Trump’s policy has shifted from that of his predecessor, Barack Obama, who had publicly criticized the authorities of the tiny Gulf state.

“In March 2017, President Trump told Bahrain’s King Hamad ‘there won’t be strain with this administration’: Bahrain appears to have interpreted this statement as a green light to pursue its repression,” the report said.

Bahrain has stepped up a crackdown on critics, shutting down two main political groups, revoking the citizenship of the spiritual leader of the Shi’ite Muslim community and jailing rights campaigners. It denounced attempts by previous U.S. and UK governments to intervene in its campaign.

In July, a Bahraini court sentenced rights campaigner and prominent activist Nabeel Rajab to two years in jail for allegedly making “false or malicious” statements about Bahraini authorities. Rajab is facing another trial and risks a further 15 years in prison for tweeting.

“Using an array of tools of repression, including harassment, arbitrary detention and torture, the government of Bahrain has managed to crush a formerly thriving civil society,” Philip Luther, Amnesty International’s director for the Middle East and North Africa, said in a statement.

Amnesty said it had received reports of nine cases of government critics being tortured in detention, eight of them in May 2017 alone.

Bahrain has been a flashpoint since the Sunni-led government put down Arab Spring protests in 2011. The kingdom, most of whose population is Shi’ite, says it faces a threat from neighboring Shi’ite theocracy Iran.

It accuses the Islamic Republic of radicalizing and arming some members of its majority Shi’ite population in an effort to bring about the downfall of the ruling Al Khalifa family.

Tehran denies any meddling in Bahrain.
