Chanting "Stop killing Rohingya Muslims", they marched in Dhaka amid tight security Friday as the violence in Myanmar's Rakhine state escalated, forcing thousands to leave their homes.
The government's de facto leader, Nobel Peace Prize laureate Aung San Suu Kyi, has made few public remarks on the crisis.
Rohingya community leaders said hundreds of families had taken shelter in camps in the Bangladeshi border towns of Teknaf and Ukhia, many hiding for fear they would be sent them back to Myanmar.
"While there are more than 30,000 registered refugees in the country, authorities estimate that 300,000 to 500,000 unregistered Rohingya are also already living in Bangladesh", she said.
The government has been urging global communities to mount pressure on Myanmar to settle the refugee issue, highlighting crimes committed by Rohingya refugees who have been given shelter in Bangladesh earlier and living for decades.
The Rohingya Muslim minority in Myanmar has been a target of a genocidal campaign for years.
It says alarming reports are being received from the ground that people are slowly starving to death.At least 160,000 Rohingya are in desperate need of food, life-saving medical assistance and other forms of aid.
"Indeed, according to the existing charter, we can not interfere in the internal affairs of another country, but we want to tell them that the people of Malaysia want the Myanmar government to be concerned with the Rohingya in Myanmar", he said.
"The fact that it?s practically impossible to verify or confirm any of these reports underlines the intensity of Rakhine state?s isolation from worldwide view".
The trio spent four days hiding in the hills with hundreds of other Rohingya families, before they found a boat owner willing to take them to Bangladesh.
Witness accounts tell of troops allegedly "killing men, shooting them, slaughtering children, raping women, burning and looting houses" as they force people from the Rakhine state and around, to flee to the Bangladeshi border. They strongly desire to return to their ancestral homeland of Arakan as soon as possible and live a life in peaceful-coexistence with other ethnic groups, as responsible citizens of Myanmar, rather than to live in humiliation as refugees in alien lands.
Meanwhile, Human Rights Watch said that this week, using satellite images, it had identified more than 1,000 houses in Rohingya villages that had been razed in northwestern Myanmar.

It is imperative for the worldwide community to alleviate the suffering of the Rohingya who have fled Myanmar and those still in Rakhine.
Malaysia, which has a sizable Rohingya community, has said it will "will summon the ambassador of Myanmar to convey the government of Malaysia's concern over this issue", according to a foreign office statement.
Soldiers have also been accused of serious human rights abuses, including torture, rape and executions, which the government has flatly denied.
Fleeing civilians have described horrendous treatment meted out against them by the army, in what McKissick described as "collective punishment of the Rohingya minority".
