Human Rights Watch and Amnesty International had accused the Security Council on Tuesday of ignoring large-scale "ethnic cleansing" of the Rohingyas and demanded that it hold an open meeting and urge an end to the violence.
It was unclear whether Murphy would be visiting Rakhine State, and Zaw Htay declined to say whether any request by the USA diplomat would be accepted.
"I call on the Myanmar authorities to suspend military action, end the violence, uphold the rule of law, and recognise the right of return of all those who had to leave the country", UN Secretary-General Guterres told reporters at the UN headquarters in NY.
A trawler carrying Rohingya Muslims fleeing Myanmar capsized Tuesday in the Naf River on the border with Bangladesh, leaving two children dead.
Instead of attending the UN General Assembly's ministerial sessions, which open on Tuesday and run through September 25, Ms. Suu Kyi will give a speech in Myanmar next week that will cover the same topics she would have addressed at the United Nations, presidential office spokesman Zaw Htay said.
Khalsa Aid said that they had got the permission from the Bangladesh government to serve meals to the refugees, media report said.
Since August 25, the Myanmar military has significantly stepped up its clampdown on the persecuted Muslim community, mainly based in the country's western Rakhine State, following a series of attacks on army and police checkpoints there.
Some Rohingyas say although they are afraid to return, they are not ready to abandon their homes altogether and become refugees in Bangladesh. "The humanitarian situation is catastrophic", he said.
"We are urgently appealing for more funds (for assistance)", he said.
The violence in Rakhine and the exodus of refugees is the most pressing problem Nobel Peace laureate Aung San Suu Kyi has faced since becoming national leader past year.
United Nations human rights chief Zeid Ra'ad Al Hussein on Monday described what was happening in Rakhine state as a "textbook example of ethnic cleansing".
