The United Nations said none of the 15 council members objected to adding al-Nusra as an alias of al-Qaida terrorist group by the deadline Thursday.
The decision by the Security Council committee monitoring sanctions against al-Qaida officially published on Friday, subjecting al-Nusra to a global arms embargo and asset freeze.
Al-Nusra has emerged as the most organized militant group fighting against President Bashar Assad's government. It joined ranks with al-Qaida in Iraq in early April.
On May 16, al-Nusra leader Muhammad al-Jawlani was also designated as a "global terrorist," subjecting to more sanctions.
According to political analysts, the so-called Free Syrian Army (FSA) closely cooperates with the al-Qaeda-linked terrorist group al-Nusra Front under the auspices of the US and the Israeli regime.
“Anybody calling himself Free Syrian Army is in fact a representative of al-Nusra Front,” said American author and historian Webster Griffin Tarpley in an earlier interview with Press TV.
“We are getting reports every day of more and more units of the so-called FSA, showing their true colors or going over to al-Nusra and proclaiming themselves full-fledged terrorists, al-Qaeda disciples, death squads in every sense of the word,” Tarpley stated.
