This is no doubt a barbaric action to kill people who are going to deliver food to people in war zone. I would like to draw attention that there are press reporters, rescue workers, doctors from Palestine and from Arab countries are also killed while performing there duties. The ironry is that no one from USA or EU condemned there killings. All lives matter equally whether it's Arab or someone from West.
We saw slogan of Black lives matter when George Floyd was killed in USA and it was accepted worldwide. But so many killings in Palestine have no effect on the world.
