Mosul's children were shouting beneath the rubble. Nobody came

Coalition bombs buried more than a hundred people in the ruins of three houses and raised fresh questions about US rules of engagement

By the time rescuers finally arrived no one was left alive. For almost a week desperate neighbours had scraped through the rubble, searching for as many as 150 people who lay buried after three homes in a west Mosul suburb were destroyed by coalition airstrikes.

The full picture of the carnage continued to emerge on Friday, when at least 20 bodies were recovered. Dozens more are thought to remain buried in what could turn out to be the single most deadly incident for civilians in the war against Islamic State (Isis).
