A truck bomb packed with tanks of toxic chlorine gas exploded in a market in a Shiite enclave in the war-torn Iraqi province of Diyala and killed 32 civilians, police said on Wednesday.
Officers and local officials said the bombers struck at around 7.30 pm (1530 GMT) on Tuesday in Abu Saydah, in a region northeast of Baghdad which is a battleground between US forces, Sunni insurgents and Shiite militia.
"A small van with gas canisters exploded in a crowded market, there were many people dead at the scene," said Captain Sadiq Mohammed. Other officials, speaking on condition of anonymity, spoke of 32 dead and 65 injured.
Interior ministry operations director Brigadier General Abdel Karim Khalaf confirmed that there had been an explosion followed by two mortar attacks on Abu Saydah, but was not able to give an official death toll.
