The Organization for the Prohibition of Chemical Weapons and the UN already have a team of 60 experts and support staff in Syria destroying Syria's production facilities while the country's civil war rages on.
The 15-member Security Council sent a letter to Ban today backing his plan on carrying out the full eradication of Syria's banned chemical arms.
"The Security Council authorises the establishment of the OPCW-UN join mission as proposed," said the letter, a copy of which was obtained by AFP.
"This recognition occurs nearly 100 years after the first chemical attack -- and 50 days after the appalling use of chemical weapons in Syria. Far from being a relic of the past, chemical weapons remain a clear and present danger," Ban said in a tribute to the OPCW.
Ban said in a draft plan sent to the Security Council that up to 100 experts will be needed to carry out the mission aiming to destroy Syria's sarin, mustard gas and other chemical weapons by the middle of 2014.
A chemical weapons attack in Damascus on August 21, which left hundreds dead, sparked an international crisis that led to threats of a US military strike against Syrian government targets.
However the Security Council passed a resolution on September 27 backing a Russia-US plan to destroy President Bashar al-Assad's chemical weapons.
The team has been doubled to about 60 people in recent days, the UN said Friday.
The team "has made good progress in verifying the information submitted" by the Syrian government, said a UN statement.
