ASTANA, Kazakhstan, Jan. 3 (UPI) -- Some Syrian rebel groups said they may not engage in proposed peace negotiations with Syrian President Bashar al-Assad over alleged violations of a recent cease-fire.
Moderate militant forces under the Free Syrian Army umbrella rebel coalition threatened to boycott the Russia and Turkey-backed peace talks over the alleged violations, adding that any territorial advances by Assad's forces or Iran-supported militias would end the cease-fire that began Friday.
