Syria has handed over the remaining 100 tonnes of toxic material it declared to the global chemical weapons watchdog, clearing the way for destruction of the stockpile at sea, sources said yesterday.

The international chemical weapons watchdog says it will send a team to Syria to investigate recent allegations about the use of chlorine gas in the country’s civil war.

Syria has provided video and photographic evidence that shows a chemical weapons site near war-torn Aleppo has been dismantled and abandoned, weapons inspectors have said.
