"We also documented the fact that Hezbollah launched thousands of rockets on densely populated cities, towns and villages in Northern Israel, using a variety of unguided rockets, often referred to as ?Katyushas,? which cannot be targeted at military objects with any degree of precision because of their limited technology.
When firing these rockets into civilian areas, Hezbollah knew that the likelihood of hitting a military target was slim to none, while the likely result would be the death and injury of civilians. Such attacks were at best, indiscriminate attacks on civilian areas, and at worst, direct attacks against civilians.
Either way, they were serious violations of international humanitarian law and probable war crimes."
Because of Hezbollah?s secrecy, little is known about the conduct of its forces inside Lebanon and whether its own actions put Lebanese civilians at risk. Human Rights Watch?s research found that on a number of occasions Hezbollah unjustifiably endangered Lebanese civilians by storing weapons in civilian homes, firing rockets from populated areas, and allowing its fighters to operate from civilian homes.
Hezbollah also used children as active combatants, another violation of the law. "
In the wake of the war, the United Nations Human Rights Council, primarily at the instigation of Arab and Muslim member states, moved swiftly to establish a commission of inquiry to investigate Israel?s violations of the laws of war. But in a startling display of self-defeating bias, it refused to examine Hezbollah?s conduct.
That one-sided response undermined the credibility of the UN?s strongest human rights mechanism at a time when it is most needed to compensate for Lebanon?s inability or unwillingness to undertake such an investigation on its own. As a result, no official body is investigating Hezbollah?s conduct during the hostilities or demanding that Hezbollah answer for it."
