"The OPCW confirmed today that 74.2 per cent of Syria's entire stockpile of chemicals has now been destroyed," The Hague-based Organisation for the Prevention of Chemical Weapons said in a statement.
Around 190 tonnes of mainly chemical precursors, used for making nerve agents and a small amount of hydrochloric acid were destroyed at a commercial facility at Ellesmere Port near the northwestern city of Liverpool, the OPCW said.
The chemicals made up around 15 per cent of the stockpile removed from Syria.
The remaining 600 tonnes of Syria's declared chemical arsenal was being destroyed on board a US military ship, the Cape Ray.
The Pentagon said two weeks ago that American specialists have so far neutralised about a quarter of the chemical DF, a precursor to make lethal Sarin gas.
After a global outcry over deadly chemical attacks in a Damascus suburb last year that may have killed as many as 1,400 people, the Syrian regime of President Bashar al-Assad agreed to an international plan to destroy its chemical weapons stockpile.
Effluent from the process on the Cape Ray will afterwards be destroyed in Finland and Germany, it added.
