A Bahraini opposition protester is trying to overturn immunity from prosecution for Bahrain's Prince Nasser bin Hamad Al Khalifa, whom he accuses of involvement in torturing prisoners in the Gulf state.

The case was launched in the British courts in 2012, but a judge's order barred identification of both the defendant and the claimant.

The High Court ruled Friday that Prince Nasser could be named.

The claimant remains anonymous and has been given permission to challenge a ruling by British prosecutors that the prince has state immunity from prosecution.

The claimant's lawyers said Monday that the case is due to be heard later this year.

Dozens of people have been killed since Bahrain's Shiite majority launched protests in February 2011 for a greater political voice in the Sunni-ruled kingdom.
