Clashes erupted between Rohingya militants and Myanmar security forces in the Rakhine State after militants attacked border police. The fighting has killed 89 people and forced thousands of civilians - Rohingya and ethnic Rakhine - to flee their homes.
Expressing concern over the escalating tensions in the region, Guterres said that he hoped those responsible would be brought to justice.
Guterres termed the attacks as "unacceptable" and reiterated the "importance of addressing the root causes of violence, in particular issues related to identity and citizenship, and reducing inter-communal tensions," his spokesperson said.
It said the forces must protect civilians at all times, in line with international humanitarian and human rights law while taking the necessary measures to curb attacks by criminal elements in the region.

Rohingyas are Muslim Indo-Aryan people from the Rakhine State in Myanmar. According to the Rohingyas and some scholars, they are indigenous to Rakhine State, while other historians claim that the group represents a mixture of precolonial and colonial immigrations.
The official stance of the Myanmar government, however, has been that the Rohingyas are mainly illegal immigrants who migrated into Arakan following Burmese independence in 1948 or after the Bangladesh liberation war in 1971.
