Peru's Supreme Court has reduced the prison sentence of President Ollanta Humala's brother who led a failed rebellion six year ago.

The court on Wednesday trimmed former Antauro Humala's sentence from 25 to 19 years.

Antauro Humala was sentenced for leading a 2005 armed uprising against then President Alejandro Toledo that killed six people, including four police officers.

His lawyers say they will appeal the ruling in an effort to further reduce the sentence.

President Humala has not released a statement on his brother's reduced prison term.

Antauro Humala is now scheduled to for release in 2024.
