Canada has added 12 more Russians and Ukrainians to its list of individuals facing economic sanctions and travel bans, the Canadian prime minister's office said in a statement.
The measures, which followed a similar move by the European Union on Monday, target "six Russian and six Ukrainian individuals who have facilitated Russia's violation of Ukrainian sovereignty and territorial integrity," Canadian Prime Minister Stephen Harper said in an online statement.
The list released by Harper's office included the Russian Army's Chief of General Staff Valery Gerasimov, acting Sevastopol Governor Sergei Menyailo and Minister for Crimean Affairs Oleg Savelyev
Two deputy speakers of the State Duma — Sergei Neverov and Lyudmila Shevtsova — and a leader of armed pro-Russian separatists in eastern Ukraine are also included on the list.
The Ukrainians on the list include leaders of the self-proclaimed Donetsk republic, two separatist leaders from Luhansk, and the Federation Council member from Crimea, Olga Kovatidi.
"Russia's illegal occupation of Ukraine and provocative military activity remains a serious concern to the international community," Harper said in the statement. Calling the Ukrainian crisis a "grave breach of international peace and security," he added that more international measures will follow "until Russia de-escalates."
"The [Russian President Vladimir] Putin regime's aggression will not go unanswered," Harper said in the statement.
The EU extended its sanctions list to include two more Crimean companies and 13 Russian and Ukrainian individuals on Monday.
