Bahrain Mirror: The health of a prominent activist jailed in Bahrain is failing and authorities are not providing medical care, international human rights groups said.

The rights groups, notably International Federation for Human Rights (FIDH), said in a statement issued on Thursday that Bahrain's government has denied healthcare to and "detained, imprisoned, tortured... or forced into exile".

The HR organisations said they had evidence authorities withheld medication for Rajab, who has been hospitalised multiple times in recent years, "in a clear attempt to threaten his security and integrity".

"Recently alarming signals have multiplied raising security concerns regarding his detention condition," said Dimitris Christopoulos, president of FIDH, an international consortium of 184 non-governmental organisations from around the world.

"The government should put a stop to these tactics and immediately release him. We seriously fear for his life," he added.

Bahraini authorities have jailed dozens of activists and disbanded opposition groups since 2011.
