Aid to Abbas

Ha'aretz claims to have documents proving that the United States is providing aid to Palestinian forces loyal to President Mahmood Abbas. There have been a lot of stories like this floating around, and I'm pretty sure that both Israel and the United States want to strengthen Fatah against Hamas in the potential Palestinian civil war. In this case, however, I feel like more context is needed for the story. Isn't the United States supposed to provide funds for Palestinian security services as part of peace agreements? If so, then is this aid part of that? Was it part of the frozen aid that is now being unfrozen, thus showing favoritism to Fatah in that respect? Finally, if this really was some sort of big secret, why leak it, making Abbas appear an American puppet?
