BAGHDAD, July 18: The death toll from a bombing at a crowded marketplace in eastern Iraq climbed to as many as 130 on Saturday, Iraqi officials said, marking the Islamic State's worst single bombing attack on a civilian target in the country. Imad Muthan, a spokesman for the Diyala provincial council, said that in addition to those killed, 20 more people were missing after a suicide bomber drove a truck packed with explosives into a market in Khan Bani Saad on Friday night.
