BANGKOK (AP) — Search teams in Myanmar recovered more bodies from the ruins of buildings on Friday, a week after a massive earthquake killed more than 3,300 people, as the focus turns toward the urgent humanitarian needs in a country already devastated by a continuing civil war.

United Nations humanitarian chief Tom Fletcher, who is also the emergency relief coordinator, arrived Friday in Myanmar in an effort to spur action following the March 28 quake.

Ahead of the visit, U.N. Secretary-General Antonio Guterres appealed to the international community to immediately step up funding for quake victims “to match the scale of this crisis,” and he urged unimpeded access to reach those in need.

“The earthquake has supercharged the suffering with the monsoon season just around the corner,” he said.

Myanmar’s military and several key armed resistance groups have all declared ceasefires in the wake of the earthquake to facilitate the flow of humanitarian aid.

But the U.N.’s Human Rights Office on Friday accused the military of continuing attacks, claiming there were more than 60 attacks after the earthquake, including 16 since the military announced a temporary ceasefire on Wednesday.

“I urge a halt to all military operations, and for the focus to be on assisting those impacted by the quake, as well as ensuring unhindered access to humanitarian organizations that are ready to support,” said U.N. High Commissioner for Human Rights Volker Türk said. “I hope this terrible tragedy can be a turning point for the country towards an inclusive political solution.”

Announcing its ceasefire, the military also said it would still take “necessary” measures against resistance groups, if they use the ceasefire to regroup, train or launch attacks, and the groups have said they reserved the right to defend themselves.
