A group of Palestinian activists in the UK could be imprisoned after a protest outside a factory owned by a subsidiary of Israeli drone manufacturer, Elbit Systems. Five protesters were arrested in July after the demonstration in the West Midlands town of Shenstone and later charged with a breach of the Trade Union and Labour Relations. Operations at the UAV Engines Ltd plant were shutdown for two days starting July 6 with protesters laying out mock coffins outside the factory and laying on the ground outside its gates. The specific offence the activists are accused of carries a sentence of up to six months in prison and a fine of up to 5,000 British pounds ($6,410). A court hearing on Friday was adjourned pending a review of the charge by prosecutors with the possibility that the current charge may be dropped and a new one added.
