The Assad regime is behind the majority of over 330 alleged chemical weapons use in Syria over the last eight years, according to a German-based report.
In a report titled "Nowhere to Hide: The Logic of Chemical Weapons Use in Syria", Berlin-based Global Public Policy Institute (GPPI) said on Sunday that some 336 chemical attacks were recorded in Syria since the start of the civil war.
Nearly 98 percent of the attacks were carried out by the regime forces, the report added.
The Daesh terror group, meanwhile, conducted six of the chemical attacks in the civil war-torn country.
The report said that approximately 90 percent of the attacks occurred after the August 2013 chemical attack killed hundreds of people in the suburbs of the Syrian capital Damascus what then-president Barack Obama had previously called a “red line,” saying it demanded a military response against the Assad regime.
During the first three years of the conflict, Washington's Syria policy was based on Obama's demand that Syrian leader Bashar al-Assad step down; economic sanctions imposed on the regime; and frequent warnings against crossing “red lines”.
Syria has been locked in a vicious civil war since early 2011, when the Assad regime cracked down on protesters with unexpected ferocity.
Since then, hundreds of thousands of people are believed to have been killed and millions more displaced by the conflict.
