A wave of attacks in Iraq has killed at least 28 people, raising the July death toll to 638, security and medical officials say.On Tuesday night, bombs went off when hundreds of people gathered for prayers at four Sunni mosques, leaving 12 worshippers dead and dozens more injured, AFP reported. Two mosques were attacked in the northern city of Kirkuk, one was bombed in the Dura area of south Baghdad, and another in Kut, southeast of Baghdad. Earlier in the day, terrorist attacks in the provinces of Nineveh, Kirkuk, Diyala and Salaheddin killed 16 people, including seven policemen, and injured many others. The incidents are the latest in a string of attacks across Iraq that have left more than 2,900 people dead since the beginning of April. In the first 14 days of Ramadan, more than 400 people have lost their lives in violence across Iraq. In an interview with Press TV on Monday, an international human rights lawyer said that foreign powers are attempting to fabricate and benefit from Shia-Sunni discord in Iraq and elsewhere, seeking to see the Muslim world weakened in the wake of such rifts. “Who benefits is of course the key issue. It’s really not the people of Iraq, it’s not the Sunnis, it’s not the Shia[s]. It is external powers that want to exploit and create division. Those are the parties that benefit,” said Canada-based attorney Edward Corrigan. “It’s certainly not the people in the region [that benefit from sectarian conflicts]; it’s not Iran; it’s not Iraq; it’s not the people of Syria, which are now witnessing the destruction of their state and where there has been attempts to provoke similar sectarian conflict in Lebanon,” he added.
