Earlier, it was reported that the Bangladeshi government had made a decision to not allow the humanitarian aid to the Rohingya refugees in Bangladesh.
Zeid called on the worldwide community for a robust mechanism to address such violence. Malaysia, which has accepted thousands of Rohinyga refugees and has sent humanitarian aid to them, says the crisis must end.
However, Ms Suu Kyi's spokesman told the BBC that the latest allegations were extremely serious.
Numerous testimonies "confirmed that the army deliberately set fire to houses with families inside, and in other cases pushed Rohingyas into already burning houses", the report states.
"The Investigation Commission headed by the Vice President will look into it". Violence in 2012 between ethnic Rakhine Buddhists and Rohingya Muslims left scores dead and forced well over 100,000 people, mostly Rohingya, to flee their homes for refugee camps, where most still remain.
One mother recounted how her five-year-old daughter was murdered while trying to protect her from rape.
The report, which will raise pressure on the governing party of Nobel Peace Prize-winning Aung San Suu Kyi, is based on harrowing accounts from over 200 people among an estimated 66,000 Rohingya who have fled to neighboring Bangladesh since October, when Myanmar's military began a crackdown following attacks on border posts.

Around 13 global non-government organizations, led by Putera 1Malaysia Club, sent off a relief ship Friday to deliver humanitarian and medical aid to the Rohingya Muslim minority in Rakhine, Myanmar. Plans to deliver the remainder to Rakhine state, where the Rohingya are located, and across the border in Bangladesh, appeared blocked.
Rights office spokeswoman Ravina Shamdasani said the vast majority of the people interviewed reported witnessing killings. Over half of the 101 women interviewed experienced rape and other forms of sexual violence.
"This is an historic moment.a noble effort that shows that all the pain and suffering of Rohingya in Myanmar will not go ignored", Prime Minister Najib Razak said at the port.
Zeid called for a robust reaction from the worldwide community and said Myanmar must accept responsibility for committing grave human rights violations against its own people.
