Dhaka: The international community has urged the Myanmar authorities to address the root causes of the violence in its Rakhine State and appealed all to help Bangladesh cope with the refugee influx.

UN High Commissioner for Human Rights Zeid Ra'ad Al Hussein on Tuesday expressed concern that more than 8,700 Rohingya Muslims have fled Myanmar into Bangladesh since the recent attacks, adding to the tens of thousands who have been arriving in Bangladesh since October 2016.

This latest round of violence comes after the attacks on Myanmar security forces on August 25.

He appealed to the international community to help Bangladesh cope with the refugee influx.

"I call on the government of Myanmar to follow the recommendations of the Advisory Commission on Rakhine State, headed by Kofi Annan, for an integrated and calibrated response to the situation in Rakhine State, to address rather than sacrifice human rights concerns in the interest of maintaining peace and order," he said.

The UNHCR mentioned that Bangladesh has hosted refugees from Myanmar for decades saying as of Sunday last it was estimated that some 5,200 people have entered Bangladesh from Myanmar since Thursday, according to UNHCR statement a copy of which obtained by UNB.

Meanwhile, UN Secretary General Antonio Guterres has urged the Bangladesh authorities to continue to allow the Rohingyas fleeing violence to seek safety in Bangladesh.

He made the appeal recognising that Bangladesh has hosted generously refugees from Myanmar for decades.

"The Secretary-General is deeply concerned at the reports of civilians being killed during security operations in Myanmar's Rakhine State," Spokesman for the Secretary-General Stephane Dujarric quoted the UN boss as saying.

"The United Nations stands ready to provide all the necessary support to both Myanmar and Bangladesh in that regard," he said.

The Secretary-General fully supports the recommendations of the report by Kofi Annan and urges the government to effectively implement them, he said.

The Secretary-General, who condemned those attacks, reiterated the importance of addressing the root causes of the violence and the responsibility of the government of Myanmar to provide security and assistance to those in need, according to the statement issued on Myanmar a copy of which UNB obtained.

"Many of those fleeing are women and children, some of whom are wounded," said the Spokesperson.

The UN chief called for humanitarian agencies to be granted unfettered and free access to affected communities in need of assistance and protection.

Zeid expressed concern over claims by Myanmar State Counsellor's Office that international aid workers were complicit in or supporting the attacks. "Such statements are irresponsible and only serve to increase fears and the potential for further violence," he said.

Zeid said he is extremely concerned that the unsupported allegations against international aid organisations place their staff in danger and may make it impossible for them to deliver essential aid.

Bangladesh has sought continued US support to resolve Rohingya crisis as more Rohingyas fleeing violence to seek safety in Bangladesh.

Foreign Minister AH Mahmood Ali raised the issue during his meeting with visiting acting assistant secretary of US Department of State for South and Central Asian Affairs Alice Wells on Tuesday.

While discussing the situation in Rakhine, the acting assistant secretary said the current situation in Myanmar is 'quite concerning'.

The Foreign Minister described the evolving situation there, including the recent initiatives taken by the government of Bangladesh in this regard.

He also underlined Bangladesh's full support to the report of the Advisory Commission on Rakhine State led by Kofi Annan and hoped that Myanmar government would do the needful keeping in view the recommendations made in that report.

UNHCR, the refugee agency of the United Nations, has urged Bangladesh to open borders for people fleeing violence in Myanmar's Rakhine State.

"UNHCR believes it's of the utmost importance that it (Bangladesh) continues to allow Rohingya fleeing violence to seek safety there," said UNHCR spokesperson Adrian Edwards on Tuesday at a press briefing at the Palais des Nations in Geneva.

The UNHCR also called on the international community to support Bangladesh in doing so, with all necessary aid and other help, according to UNHCR statement a copy of which obtained by UNB.

In light of the dramatic worsening since Friday of the situation in Myanmar's Rakhine state, the UNHCR has communicated to the government of Bangladesh its readiness to support Bangladesh in helping refugees flee across the border.

Several thousand were reported to be in locations along the Myanmar side of the border, it said.

On the Bangladesh side of the border, some people are in cordoned off areas near the border, and others are mainly in Kutupalong area.

The UN agency said most are women, children, or the elderly, and there have been reports of wounded people among them.

Aid efforts involving the Bangladeshi authorities, local communities, UNHCR partners and NGOs have been under way, including arrangements of food, water, and medical help to the new arrivals.

"UNHCR is grateful to the Bangladeshi authorities for the support being provided. Rapid needs assessments are being planned, however with the precarious situation inside Myanmar we are concerned that numbers of people needing help may rise further over the coming days," Edwards said.

Meanwhile, in Myanmar's Rakhine State access to populations in need of help is severely restricted. "We're appealing to the Myanmar authorities to do everything possible to facilitate humanitarian help and ensure the safety of our staff," Edwards said.
