"I saw the blast and the aftermath, many people were hurt and shops were damaged. What did they do to deserve this? All of them have families to look after."

These blasts were among a series of attacks across Baghdad on Wednesday, killing scores and wounding dozens more.

More than 1,000 Iraqis were killed in July, the highest monthly death toll since 2008, according to the United Nations.

Iraqis have suffered extreme violence for years, but since the start of the year the targeting of civilians has dramatically increased.
