At least 31 people were killed and dozens of others injured in Myanmar after an airstrike by the ruling junta hit a major hospital in the western state of Rakhine, according to witness, aid workers and the Arakan Army rebel group.

The hospital was struck by bombs dropped by a military aircraft late on Wednesday, a spokesperson for the Arakan Army said Thursday.

The rebel group largely controls the state, which borders Bangladesh, but is still battling the military junta in parts.

 What do we know about the airstrike in Rakhine state?

"Yesterday's airstrike by the terrorist Myanmar junta on public hospitals in Mrauk-U on December 10 — International Human Rights Day— is yet another example of how the fascist regime in Naypyidaw blatantly kills its own citizens, committing war crimes in broad daylight with no regard for human life," the United League of Arakan (ULA) told DW.

The Arakan Army is the armed wing of the ULA.

Several of those killed were patients. Around 70 others were injured, the ethnic minority separatist group said. 

Aid worker Wai Hun Aung said the hospital was in complete ruins and bodies of victims lay on the ground, sharing unverified images of the scene with news agency Reuters. "The remaining patients have been moved to a safe location," he said.

The strike comes weeks before the military's set polling date for elections, December 28.

The junta is now fighting to take back territory lost to resistance groups, while the rebels have pledged to block elections in territories they control.
