>> A US-led coalition fighting Islamic State in Syria may have broken international law. That's the allegation put by rights group Amnesty International in a report on Tuesday. It claims the coalition did not do enough to prevent harm to civilians during its campaign to capture the city of Raqqa, the one time Syrian capital of the jihadist group's self-declared caliphate.
>> The people of Raqqa deserve justice and they deserve to know what went wrong. But until now, coalition officials have refused to engage in any meaningful way.>> Amnesty said it had spoken to 112 civilians from Raqqa and visited the sites of 42 strikes. It said that in four cases, detailed in its report, powerful airstrikes had hit buildings full of civilians.
>> US Marines have said that they fired 30,000 artillery shells into Raqqa. That's tantamount to indiscriminate strikes. Because each artillery rounds will have a margin of error of about 100 meters, in a city where 10 meters can make the difference between a house full of civilians and the HQ of ISIS.
>> During the battle for Raqqa, Islamic State operated among civilians and used them as human shields. The coalition has responded to previous accusations that it caused civilian casualties, saying it was careful to avoid them and investigated all claims.
