[It is] protecting and covering Jabhat al-Nusra terrorist group that is none other but a subdivision of al-Qaeda, which has commited the most horrible terrorist acts in the history of the US," the statement said.
"It seems that the White House has forgotten that, under the US law, aiding terrorism is a criminal offense," the Ministry pointed out in the statement.
