"Both government and insurgent forces have used “weapons that are guaranteed to cause civilian damage,” said Geoffrey Mock, a Middle East specialist at Amnesty International. Children account for about 20 percent of these deaths.
The Syrian government has repeatedly fired imprecise rockets and unguided bombs, according to the United Nations and other monitoring groups. Insurgent groups have used so-called “hell cannons” — improvised artillery devices fitted with explosive gas canisters that cause widespread damage.
“What we are seeing in Syria is war crime on both sides,” Mr. Mock said."
