According to the Shin bet, Hamas was behind the attempt and the explosives were to be used to manufacture improvised explosive devices for attacks within Israel .
“This is a continuation of the attempts by terrorist organizations in Gaza, mainly Hamas, to abuse the humanitarian channel and the medical aid Israel provides to Gaza residents to carry out terrorist attacks in Israel,” the Shin Bet said.
Data gathered by the Coordination of Government Activities in the Territories (COGAT) indicates that since the beginning of 2015 and mid-2016, more than 360,000 Palestinians entered Israel for humanitarian needs and approximately 1,000 Palestinian physicians received medical training in Israel or abroad. The Civil Administration says, "We see medical care as the highest priority and there is no compromise on the subject; we're doing whatever it takes to save a life.”
If only Hamas felt the same way.
