After the university published its findings, an international campaign was launched against the use of lethal gases and shotguns by the al-Khalifa regime’s thugs against people.

Several founding members of the campaign, including Prof Damian McCormack, Prof David Grayson and Tara O'Grady urged a total ban on the so-called CS gas, 2-chlorobenzylidene malononitrile, during the period in which Bahraini people were marking the second anniversary of the February 14 uprising against the ruling monarch.

Another online campaign, dubbed Avaaz, has launched a petition calling on two companies who had supplied the al-Khalifa regime with these lethal gases to stop the process.

According to experts, the Bahraini regime is using a poisonous form of tear gas against civilians, which it could not be allowed to use in a battlefield against armed troops.

Physicians for Human Rights (PHR) has reported that in the past 100 years which governments have been using tear gas against civilians, no country has ever abused it like Bahrain.

So far, more than 100 Bahraini protesters have been killed as a direct result of the use of those two weapons against civilians.
