DUBAI : A Bahraini court jailed nine Shias for life Monday after convicting them of making bombs for “terrorist” purposes and for their alleged involvement in a 2011 attack, a judicial source said.

Four of the defendants were in court for the verdict and the remaining five, tried in absentia, were handed a 10 additional years in jail for failing to hand themselves in. Life imprisonment in Bahrain is a 25-year-sentence. Monday’s ruling brings to 104 the number of Shias jailed since September 29 in connection with violence in the Sunni-ruled Gulf kingdom that began with the February 2011 uprising.

In court the four men had alleged that they were tortured, mistreated and held in solitary confinement, according to lawyers. The defendants found guilty of “joining a group with the intention of disturbing public order and using terrorism to endanger Bahrain’s security,” the chargesheet said.

They were also convicted of making bombs and training others how to produce them, and “owning and using explosives for a terrorist purpose and carrying out bombings to terrorise citizens.”

Bahrain’s attorney general said that investigations proved the defendants were involved in “bombings” carried out on November 22, 2011, near the Exhibition Park in the capital Manama.

The attack damaged several cars but caused no casualties. Monday’s ruling is the fifth tough sentence handed to Shias since late last month.
