A South African court ordered police to end a standoff with illegal miners and allow emergency workers to gain access to a shaft where hundreds are believed to be holed up.

The High Court in Pretoria, South Africa, said in an interim ruling that all miners underground in the mine in Stilfontein should be allowed to leave and no one should block their exit, according to state broadcaster SABC.

On Friday, the South African Human Rights Commission (SAHRC) said in a statement it was investigating the police for restricting the miners’ essential supplies.

At least one decomposed body has been recovered from the mine, police said.
