 High Representative of the Union for Foreign Affairs and Security Policy Catherine Ashton stressed the need to "hand over any unauthorised arms to the authorities immediately," in the wake of a protest on 26 March at the parliament building, to pressure lawmakers to sack the newly appointed Interior Minister Arsen Avakov because the Right Sector group believes that Avakov is personally responsible for ordering what they call a political assassination of one of their leader, Aleksandr Muzychko, who was killed in a special operation in a city of Rovno the previous evening.On 28 April, the Harper government announced further economic sanctions on nine additional Russians and two Russian banks amid escalating tensions over Ukraine.Travel bans are also being imposed on the nine individuals.
