RIYADH — Human Rights Watch on Thursday, May 15, urged Saudi Arabia to free two citizens held without trial for two years after converting to an offshoot of Islam banned in the conservative Sunni kingdom.

Sultan al-Anzi, aged 33, and Saud al-Anzi, 35, were arrested and jailed in May 2012, three months after joining the Ahmadiyya group and refusing to abandon their belief, New York-based HRW said.

The group said it urged Saudi King Abdullah back in August 2012 to release the pair but never received a response.

“Not only have Saudi authorities interfered with the personal beliefs of these two men, but they’ve left them sitting in jail for two years in legal limbo with no end in sight,” said Sarah Leah Whitson, HRW’s Middle East director.

“Saudi Arabia needs to stop policing people’s personal beliefs,” Whitson said. “King Abdullah has won acclaim for preaching religious tolerance abroad, but there apparently is no room for tolerance inside his own country.”

Under Saudi Arabia’s legal system, the penalty for apostasy is death.

According to information on the interior ministry’s online prisoner database, both men are in detention but have not been formally charged.

The Ahmadiyya community was founded in British India in the 19th century.

Its adherents follow the teachings of Mirza Ghulam Ahmad, an Indian Muslim who they believe to be the awaited Islamic messiah.
