UNITED NATIONS (Reuters) - Russia has proposed that the United Nations Security Council blacklist Syrian rebel groups Jaish al-Islam and Ahrar al-Sham for links to Islamic State and al Qaeda militants, though Washington warned such a move undermine the push for a truce.

If none of the council's 15-member Islamic State and al Qaeda sanctions committee blocks or puts a hold on the listing by 3 p.m. EDT (1900 GMT) on May 11 then the groups will be added to the U.N. sanctions list, said diplomats.
