The commentary in a daily Al-Watan newspapers says that Jordan is backing terrorists by supporting rebels.
It came a day after a video purporting to show Jordanian pilot Maaz al-Kassasbeh being burnt alive in a cage by terrorist from the ISIS group.
"The fire of the terrorist group burned the Jordanian after Amman facilitated... the entry of thousands of Salafists across its border so they could fight alongside armed groups against the Syrian Arab army," the daily Al-Watan wrote.
"Jordan is reaping the results of its support for terrorism," added the Al-Baath daily.
Syria's government accused opposition backers like Jordan, Turkey and Persian Gulf nations of fomenting extremism.
Syria's foreign ministry Wednesday condemned Kassasbeh's murder and
called on Amman to cooperate with the Syrian government against "terrorism".
It described the execution as a "despicable, terrorist crime" and urged "the government of Jordan to cooperate in the fight against terrorism like that of Daesh (ISIS) and Al-Nusra Front (Al-Qaeda's Syrian branch)".
Jordan has joined a US-led coalition carrying out air strikes against ISIS in Syria and Iraq.
Damascus has grudgingly accepted the strikes on its territory, but said the coalition will fail to defeat IS unless it cooperates with Assad's government.
