Gaza by explosions

It is not yet known who planted the bombs.

The Gaza strip has been riven by internal divisions.

During last year’s Gaza conflict, which took place in July and August, Hamas used the chaos to settle scores and carry out “horrific abuses … some of which amount to war crimes” against fellow Palestinians, according to Philip Luther, director of the Middle East and North Africa program at Amnesty International.
