If Israel admits Syrian refugees, would it need to welcome Palestinians as well?

National Infrastructure, Energy and Water Minister Steinetz admitted that if Israel takes in Syrian refugees from the Idlib province that came under the chemical attack, the leader of Palestinian Authority Mahmoud Abbas might demand that they also take in Palestinian refugees as well.  There are about 100,000 Palestinian refugees that fled Syria to Europe due to the war, as well as additional 500,000 that fled the Palestinian refugee camps in Syria.  Article also mentions that Israel approves of the airstrikes against Assad’s regime, because it sends a clear signal to Syria, as well as other rogue states that provocations and chemical weapon attacks will not be tolerated.  He also stated his concern for the events in the Egypt and the need for the civilized world to step in and help stabilize the situation, because it is dangerous for Israel, the whole Middle East, and Europe as well.
