In August 2017, United States Secretary of State Rex Tillerson spoke against the discrimination of Shias in Bahrain, saying, "Members of the Shia community there continue to report ongoing discrimination in government employment, education, and the justice system," and that "Bahrain must stop discriminating against the Shia communities." He also stated that "In Bahrain, the government continue to question, detain and arrest Shia clerics, community members and opposition politicians." However, in September 2017, the U.S. State Department has approved arms sales packages worth more than $3.8 billion to Bahrain including F-16 jets, upgrades, missiles and patrol boats. In its latest report the Amnesty International accused both, US and the UK governments, of turning a blind eye to horrific abuses of human rights by the ruling Bahraini regime. On 31 January 2018, Amnesty International reported that the Bahraini government expelled four of its citizens after having revoked their nationality in 2012; turning them into stateless people. On 21 February 2018, human rights activist Nabeel Rajab was sentenced to a further five years in jail for tweets and documentation of human rights violations. On behalf of the ruling family, Bahraini police have received training on how to deal with public protests from the British government.
