RNA - The Court of Cassation also stripped 47 of the defendants of their citizenship, Bahrain’s official news agency BNA, citing an official statement, reported.
The court also upheld life terms for 19 convicts and sentenced 37 others to between five and 15 years in jail.
The statement said the defendants were found guilty of forming a “terror cell” that carried out a number of attacks, killing at least two policemen and wounding several others.
They were also convicted of “smuggling weapons by boat, attacking a prison and helping a number of inmates flee”.
Thirty-six of the convicts, including the two sentenced to death, are being held in jail, while the rest were sentenced in absentia.
Separately, the same court upheld lengthy jail terms against 19 dissidents on charges of espionage and plotting to overthrow the ruling regime.
The court confirmed life terms for eight of those convicted, 15-year jail terms for nine and 10-year terms for two others, with the citizenship of 15 of them revoked.
Thousands of anti-regime protesters have held demonstrations in Bahrain on an almost daily basis ever since a popular uprising began in the country in mid-February 2011.
They are demanding that the Al Khalifah regime relinquish power and allow a just system representing all Bahrainis to be established.
Manama has gone to great lengths to clamp down on any sign of dissent. In mid-March 2011, troops from Saudi Arabia and the United Arab Emirates were deployed to assist Bahrain in its crackdown.
Scores of people have lost their lives and hundreds of others sustained injuries or got arrested as a result of the Al Khalifah regime’s crackdown.
In early March 2017, Bahrain’s parliament approved the trial of civilians at military tribunals in a measure blasted by human rights campaigners as being tantamount to imposition of an undeclared martial law countrywide.
Bahraini monarch King Hamad bin Isa Al Khalifah ratified the constitutional amendment in early April 2017.
