Amnesty International says Saudi Arabia is making use of the death penalty to crush opposition figures, as a crackdown led by Crown Prince Mohammed bin Salman.
The London-based rights group said Saudi Arabia’s public prosecutor was seeking the death penalty for more people.
Saudi officials have also intensified crackdown in the country's Shia-populated Eastern Province.
Eastern Province has been the scene of peaceful demonstrations since February 2011. Protesters have been demanding reforms, freedom of expression, the release of political prisoners, and an end to economic and religious discrimination against the oil-rich region.
