The international Red Cross leader said Tuesday humanitarian help alone would not solve the Rohingya refugee crisis and inclusive political solutions are needed for the 700,000 people who fled Myanmar violence to Bangladesh.

The U.N. has said the Myanmar military crackdown on Rohingya Muslims last August in retaliation for an insurgent attack was "ethnic cleansing." Myanmar and Bangladesh have signed an agreement for repatriating refugees, but its implementation is uncertain due to safety, verification and other concerns.

President of the International Committee of the Red Cross Peter Maurer visited Rakhine state in Myanmar where the refugees once lived as well as the camps where they live now in Bangladesh's Cox's Bazar district. He said people in both places were suffering.

"I met those who stayed and those who left, and it is clear that people are suffering on both sides," he said. "People lack secure housing, electricity, latrines, medicine and health care. There are few options for people to earn an income to allow them to move beyond aid and emergency conditions."

Maurer also said the conditions for repatriation to happen were tough. "The conditions are simply not there for large numbers of people to return home," he said.

The Rohingya have faced state discrimination for generations in Buddhist-majority Myanmar. Maurer said their return would require "steps towards ensuring freedom of movement, access to basic services, freedom to undertake economic activity and access to markets in Rakhine, and most importantly trust in security arrangements for returnees," he said.

He said while he was in Myanmar, he met Muslims, Buddhists and Hindus and they described "how the social fabric and local economy have been destroyed, making people entirely reliant on humanitarian aid."

"In one village I visited, less than a quarter of the population remains, only 2,000 of the original 9,000 villagers,' he said.

In the camps in Bangladesh, over a million people live in misery, held hostage to a profoundly unsettling contradiction, he said.

"Those sheltering in the camps of Cox's Bazar live in shocking conditions that violate human dignity," he said, noting the conditions in the camps will worsen with the monsoon rains arriving.

U.N. Secretary General Antonio Guterres, World Bank Group President Jim Yong Kim and U.N. High Commissioner for Refugees Filippo Grandi all visited the refugee camps this week and promised to work with Bangladesh toward resolving the crisis.

"A better future for the people here will need inclusive political solutions, environmentally sustainable economic investment and a strong commitment to international humanitarian law and human rights," he said in a statement in Dhaka as he concluded his visit.

He met Prime Minister Sheikh Hasina on Monday and told her he found a positive attitude in Myanmar toward resolving the crisis, Hasina's press secretary Ihsanul Karim said.
