Although they don't broadcast it, Iran, Turkey, and Qatar do support Hamas. I can't help but think Iran and their proxy Hezbollah are using this opportunity to shore up their forces in Syria to launch another missile attack on the Israeli Golan Heights. Oil and Defense are the places to be.
Re: Israeli forces kill 61 Palestinians during deadly Gaza protests
I don't think Hamas will start firing rockets just yet. There will be a lot of aid coming into Gaza now. While no country is going to directly fund a terror group like Hamas, much of that foreign aid that goes into Gaza will end up getting into their hands anyway which will allow them to build up their arsenal of weapons, anti-israel propaganda, etc. even more.
