Here's video of Abbas welcoming the terrorists as heroes and his speech at the ceremony.
During his speech Abbas said "We promise that it will not be the last time, but there will be a batch of heroes coming to us all the time and in the near future, God willing....This is the day the joy of all of us the joy of our people for our prisoner heroes who came out today to the light of freedom to live free, we congratulate you and congratulate ourselves with these heroes who arrived here and who arrived in Jerusalem, Gaza, and the rest will come, God willing."
He said that soon there will be a Palestinian state whose capital is Jerusalem and the Palestinian flag will fly over the minarets and churches of Jerusalem.
We know what would happen to the synagogues if he had his choice.
