The death toll from Sunday's suicide bombing in Baghdad has risen to 250, the Iraqi government says, making it the deadliest such attack since the 2003 US-led invasion. A lorry packed with explosives was detonated while families were shopping for the holiday marking the end of Ramadan. So-called Islamic State (IS) has said it carried out the suicide attack. Iraq remains under an official state of mourning following the bombing. The destruction of the area was all but complete. Bewildered local residents have held candlelight vigils and prayed for peace. Scores of people were injured, but most have been released from hospital, according to the health ministry. Reports said a lorry packed with explosives had been left near the Hadi Centre, popular with shoppers. The powerful blast engulfed the area in flames. Such was the chaos it took days for the scale of the attack to become clear.
