The Action on Armed Violence (AOAV), an organization dealing with casualties around the world, says that the number of civilians casualties from bombs and mortars have grown by over 50 percent since 2011.

According to Reuters, 43,800 people were killed or injured by explosives last year. Seventy-six percent of the victims were civilians.

"More states should speak publicly against the use of such weapons and hopefully we will end up stigmatizing it just as land mines, cluster munitions and poison gases have been stigmatized," said Iain Overton, AOAV's director of investigations.
