In footage published by the Gaza-bound ship 'Sumud' on its Instagram account, an announcement was heard before the takeover of the vessel. 'This is the Israeli Navy. Attempts to breach the lawful maritime security blockade on the Gaza Strip constitute a violation of international law,' the announcement stated. 'If you are carrying humanitarian aid, you are invited to proceed to Ashdod Port. You must change your course. It is dangerous to remain on your current course. If you continue attempting to breach the maritime blockade, we will stop your vessel and act to confiscate it through legal proceedings in court. You bear full responsibility for your actions.'
