The Israeli military authorities must end their campaign of harassment intimidation and arbitrary detention against a Palestinian activist in the occupied West Bank, Amnesty International said. Bassem Tamimi, who has been detained since his arrest at a non-violent protest against the encroachment of Israeli settlers onto Palestinian land last week, faces a further prison sentence after appearing before the Ofer Military Court on Wednesday. “Once again, Bassem Tamimi is being held solely for peacefully exercising his rights to freedom of expression and assembly. We believe he is a prisoner of conscience and should be released immediately and unconditionally,” said Ann Harrison, Deputy Middle East and North Africa Programme Director at Amnesty International. Tamimi was arrested on 24 October following a non-violent demonstration in a supermarket in Sha’ar Benjamin settlement north of Ramallah. More than 100 protesters had gathered to call for an end to the occupation and a boycott of all Israeli products. He faces charges of assaulting a police officer, participation in an unlicensed demonstration, and activity against the public order. If convicted of either of the latter two “offences”, he will also have to serve one or more suspended sentences from a previous trial: two months for participation in an unlicensed demonstration, and 17 months for “activity against the public order”. After viewing footage of the protest, the military judge ruled that he should be released to house arrest for the duration of legal proceedings. The military prosecution is appealing this decision, and he remains at Ofer prison. Tamimi was previously sentenced in May 2012 to 13 months in prison for his role in organizing regular non-violent protests against Israeli settlements in the West Bank. At the time, Amnesty International considered him to be a prisoner of conscience, and called for his immediate and unconditional release. The establishment and expansion of Israeli settlements in the occupied West Bank violates international humanitarian law.
