From the Guardian:
Adel says 10 Sunnis have been killed in his neighbourhood in the past month. In retaliation 20 Shia were kidnapped and killed by Sunni insurgents. During one week the Guardian spent in Yarmouk in May, a grocer, his two brothers and a cousin, a school guard, a generator operator, and four ministry of education employees, all Shia, were killed. Two Sunnis were killed in the same week.
“Look, a full-scale civil war will break out in the next few months. The Kurds only care about their independence. We the Sunnis will be crushed – the Shia have more fighters and they are better organised, and have more than one leadership. They are supported by the Iranians. We are lost. We don’t have leadership and no one is more responsible for our disarray than [Abu Musab al-] Zarqawi, may God curse him,” he said.
