Twenty people have been killed and 50 injured in a suspected chlorine bomb in Iraq's Diyala province, police say. The attack happened in an open-air market in the village of Abu Sayda at about 2000 (1600 GMT) on Tuesday. The words you're looking for are "filthy war crime." So far I haven't seen the words come out of AI's or HRW's mouths. All the UN special rapporteurs have remained mum.
A police spokesman in the provincial capital Baquba said doctors at a local hospital believed the nature of victims' burns suggested poison gas. Use of chlorine bombs has become more common since the start of the year, says a BBC correspondent in Baghdad.
More common in Iraq, that is. As far as I know, it's the only place in the entire world where such filthy tactics are used.
Last month a bomb using chlorine and high explosive killed 35 people in Ramadi, west of the capital. Chlorine - widely used as a cleaner and purifier in areas of poor water sanitation - is easy to obtain in Iraq.
It's easy to obtain in most places. Most places still don't use it as a weapon.
Chlorine gas burns the skin on contact and can be fatal after a few breaths. In February the United States military reported finding a bomb factory near Falluja, where chlorine car bombs were being constructed. Diyala province - with its mixed Shia and Sunni Muslim population - has been the scene of frequent violence of a sectarian nature as well as attacks by anti-US insurgents.
