A pro-democracy Bahraini protester died after a month of coma because of the inhalation pf poisonous gas shot by Al-Khalifa regime forces.

Sayyed Mohammad Kadhem was announced dead Friday after a month in hospital, a Bahraini doctor announced on his twitter page.

Kadhem slipped into a coma after he was poisoned by tear gas in a demonstration early January in the capital city of Manama.

The death of Kadhem brings the total number of people killed by government forces over four years of peaceful protests in the Arab country to at least 90.

Bahraini government’s use of tear gas has been described by many activists as excessive, with many people falling victim to the deadly canisters used by regime security forces to quell demonstrations.

Activists and human rights groups say the government’s use of tear gas is mostly indiscriminate and lethal with police forces in some cases encircling protesters and making them inhale the poisonous gas.
