Hundreds of thousands of refugees have been living in makeshift camps in Balukhali in Ukhia, Cox's Bazar.
Bangladesh is yet to sign the International Refugee Convention of 1951 and the International Refugee Protocol of 1967 and there is no rule how the refugees will live in Bangladesh and therefore, it is very hard for the government to tackle the refugee crisis, Advocate Tanjim said in the petition.
Zeid Ra'ad al-Hussein, the United Nations high commissioner for human rights, said the military's "brutal" security campaign was in clear violation of worldwide law, and cited what he called refugees' consistent accounts of widespread extrajudicial killings, rape and other atrocities.
"We are potentially going to have one of the world's largest IDP (internally displaced persons) camps in one concentrated area", a spokesman for the organisation said.
Tom Delamere, CAFOD's Programme Officer for Bangladesh, said: "Reports we have received from the United Nations and from our partner, Caritas Bangladesh, show the desperate need faced by thousands of people". They are facing challenges of food, nutrition, shelter, water and sanitation. They are homeless and hungry following a long and treacherous journey across the border.
Prime Minister Hasina will also urge the world leaders to play an effective role in stopping the genocide of the Rohingya Muslims in Myanmar.
Iranian officials have voiced readiness to construct emergency camps and field hospitals for the refugees on Bangladesh's border with Myanmar. "But also distribution of food and preparation of shelter", he added.
"People are living in these muddy, bad conditions".
Although the recruiting of terrorists to Rakhine was still new, they were gathering information on the matter, including the detention of a 38-year-old man from Malacca on September 10, he said.
They would receive 24-hour support and protection while attempts are made to find family members, it said.
"It's very hard to predict what's going to happen in the next month".
