Yeah, there's pearls being clutched over this one, but they hit almost entirely actual targets. I have a feeling the civilian death toll in Palestine has already eclipsed this several times since it happened.
The evidence indicates that those who planned and carried out these attacks could not verify who else in the immediate vicinity of the devices would be harmed at the time of the explosion, or even whether only fighters had been given the pagers and radios. Therefore, the attacks were carried out indiscriminately, would be unlawful under international humanitarian law and should be investigated as war crimes. The attacks also violated at a minimum the right to life under international human rights law, which continues to apply in situations of armed conflict, and likely other human rights, depending on the various impacts of the attack on the Lebanese population and their daily lives.
Kill awful people all they like, but they might want to do it in a country they're at war with and in a way that doesn't murder and injure Innocents. I seem to remember the violation of sovereignity and death of civilians being the very fucking reason Israel declared war in the first fuckin place.
