two children, had been injured in landmines as of 10 September. Mro people crossing the border into Myanmar have also been injured by the mines. Ceasefire and aftermath A one-month unilateral ceasefire was declared by ARSA on 9 September, in an attempt to allow aid groups and humanitarian workers safe access into northern Rakhine State. In a statement, the group urged the government to lay down their arms and agree to their ceasefire, which would have been in effect from 10 September until 9 October (the one-year anniversary of the first attacks on Burmese security forces by ARSA). The government rejected the ceasefire, with Zaw Htay, the spokesperson for the State Counsellor's office, stating, "We have no policy to negotiate with terrorists." The Myanmar government reported on 17 September that 176 of 471 Rohingya villages had been abandoned. By then it was reported that 430,000 Rohingyas had fled into neighbouring Bangladesh. The government of Bangladesh also announced plans to build shelters for 400,000 refugees and start immunisations, but began restricting the movement of some of the refugees. United Nations Secretary General António Guterres urged Myanmar State Counsellor Aung San Suu Kyi to use her planned speech to her nation on 19 September to announce a stop to the military offensive, warning that if she did not, "I do not see how this can be reversed in the future". However, U.S. diplomats—while demanding that "this persecution must stop", attempted to be supportive of Suu Kyi's fragile, new civilian-leader position in a nation still largely ruled by the military. Suu Kyi's speech was later criticised by Amnesty International as "a mix of untruths and victim-blaming". Doubt was also cast on her statement of there being no clashes after 5 September, with satellite imagery examined by Amnesty International appearing to show more than a dozen burned villages and fires since then. Myanmar's vice-president Henry Van Thio told the UN on 20 September that Burmese security forces had been instructed to avoid collateral damage and harm to innocent civilians. He also promised that human rights violations would be dealt with "in accordance with strict norms of justice." Thio added that minority groups other than the Rohingya had also fled the violence and that his government was concerned over Rohingyas fleeing despite there being no armed clashes since 5 September.
