State Counselor Aung San Suu Kyi is Myanmar's de facto leader. The 1991 Nobel Peace Prize recipient has come under international fire for failing to advocate for the Rohingya.

Myanmar is predominantly Buddhist, but it is also home to Muslim, Sikh, Hindu and Christian groups. The recent crisis in Myanmar centers on the Rohingya, a Muslim ethnic group.

Myanmar's military, which is staging the crackdown on the Rohingya, has massive power in the country. In this photo taken Aug. 31, 2016, Myanmar military commander Senior Gen. Min Aung Hlaing (L) speaks with Vice President Henry Van Thio as de facto leader Aung San Suu Kyi looks on.

Myanmar is home to a host of insurgent groups claiming to represent the interests of ethnic minorities. Some are aligned with the central government; others are negotiating for power. Still others are engaged in active fighting. This photo taken Jan. 12, 2014, shows Ta'ang National Liberation Army fighters on parade in Shan state.

Myanmar officially recognizes 135 ethnic groups under the umbrella of eight "major national ethnic races." The Rohingya are excluded from this list. Here, an ethnic Chin lawmaker leaves Myanmar's upper house of parliament on March 11, 2016.

An insurgency group calling itself the Arakan Rohingya Salvation Army attacked police and military outposts on Aug. 25, prompting Myanmar's military to crack down on the Rohingya in response. In 1992, the growth of another group, the Rohingya Solidarity Organization, sparked a crisis with Bangladesh. In this March 1992 photo, a Rohingya fighter guards an outpost on the border.

Rohingya activists rallied against the Myanmar military during its longtime dictatorship. An ethnic Rohingya dissident participates in an October 2007 candlelight vigil demanding the release of Aung San Suu Kyi, the democratic icon who largely has been silent about the Rohingya's circumstances.

Rohingya refugees have been present in Bangladesh for decades. This September 2009 photo shows an unregistered camp 400 kilometers (248 miles) southeast of Dhaka.

Rakhine Buddhists reportedly have burned thousands of Rohingya houses in western Rakhine state. Several young men walk past a burning structure on Sept. 7.

These Rohingya refugees are part of a mass exodus from Myanmar. The United Nations estimates that almost 400,000 of Myanmar's 1.1 million Rohingya have fled to Bangladesh since Myanmar's military began cracking down on the Muslim ethnic group after a militant attack on Aug. 25.
