Syrian President Bashar Assad’s government had plans in place to transfer chemical weapons to Hezbollah, according to former Syrian general turned defector, Major-General Adnan Sillu.

In an interview with the former Syrian general published in the Times of London, Sillu said that aside from plans to transfer weapons to Hezbollah, Syria had planned to use chemical weapons on the Syrian people, “as a last resort.”

"We were in a serious discussion about the use of chemical weapons, including how we would use them and in what areas," Sillu told the Times.

"We discussed this as a last resort -- such as if the regime lost control of an important area such as Aleppo," said the General.

Earlier in the week, a report in the German weekly Der Spiegel claimed that Syria tested delivery systems for chemical weapons at the end of August.

The report, which quotes various witnesses, said that the tests took place near a chemical weapons research center at al-Safir, east of Aleppo, and were carried out with the aid of Iranian officers who were flown in for the testing.

According to the report, five or six empty shells capable of delivering poison gas were fired by tanks and aircraft at the site of Diraiham in the desert, near the village of Khanasir.

The report said that scientists from Iran and North Korea are said to work in the al-Safir research center, which is Syria's largest testing site for chemical weapons.
