The current upsurge in violence threatens the safety of civilians, said the INGOs in a joint statement on Tuesday.
The signatories to the joint statement are ACTED, Action Contre La Faim, CARE International, Christian Aid, Consortium Dutch NGOs, Danish Refugee Council, Lutheran World Federation, Malteser International, MAUK-Myanmar, Mercy Corps, Norwegian Refugee Council, Oxfam, Peace Winds Japan, People In Need, Relief International, Save the Children, Solidarités International and World Vision International.
As International NGOs supporting communities throughout Rakhine State, they expressed deep concern for displaced communities and others affected by the upsurge in fighting between the "Arakan Army" (AA) and Myanmar Military.
Fighting, attacks, and reports of abuse have invoked fear and anxiety among local communities and displaced an estimated 5,000 men, women, and children, the statement reads.
"We condemn the violence and call on all sides to show restraint and ensure the protection of civilians," according to the statement.
The INGOs said humanitarian access is now extremely restricted to five key townships where violence and resulting displacement has been most pronounced.
Without effective and ongoing access, the ability of local and international organisations to provide life-saving assistance to all conflict-affected communities in central and northern Rakhine is seriously compromised, says the statement.
"We commend Rakhine civil society organisations, the Red Cross movement, and other agencies already responding to the urgent needs of displaced and other affected people."
The INGOs said they are very concerned that this response will not be sufficient to meet the humanitarian needs of an estimated 5,000 people now displaced in Buthidaung, Kyauktaw, Ponnagyun and Rathedaung, with further fighting and displacement expected.
"We stand ready to support all conflict-affected communities and complement ongoing response efforts as needed. Local and international organisations should be granted rapid, unfettered and sustained access to all affected populations to independently assess needs and provide comprehensive assistance and protection to all communities in accordance with international humanitarian and human rights law," the statement adds.
