The Palestinian President is quoted as calling the raid a “massacre”; the Hamas leader in Gaza called it a “heinous crime”.
The flotilla was organised, among others, by a Turkish human rights organisation, with some of the ships flying Turkish flags. Ankara had urged Israel to allow safe passage.
Hamas leader Ismael Haniyeh said: “The Hamas government calls on Palestinians in the homeland and the diaspora to hold marches and demonstrations of anger and protest against this heinous crime and to show full solidarity with members of the convoy.
“We call on the Palestinian Authority to stop negotiations, both directly or indirectly. It is not reasonable to continue these negotiations in light of this crime, which exceeded all limits.”
