By Phil Stewart WASHINGTON (Reuters) - U.S.-led coalition aircraft waged a series of deadly strikes against Islamic State around the city of Falluja on Wednesday, U.S. officials told Reuters, with one citing a preliminary estimate of at least 250 suspected fighters killed and at least 40 vehicles destroyed. The strikes, which the officials said took place south of the city, where civilians have also been displaced, are just the latest battlefield setback suffered by Islamic State in its self-proclaimed "caliphate" of Iraq and Syria. Turkey pointed the finger at Islamic State on Wednesday for a triple suicide bombing and gun attack that killed 41 people at Istanbul's main airport.
Britain's main opposition Labour Party headed for a leadership battle, mirroring a fight for control of the ruling Conservative Party, after the decision by voters to leave the European Union last week led to upheaval in Westminster. Angela Eagle, a senior Labour lawmaker, will announce on Thursday that she will challenge leader Jeremy Corbyn who has been facing a growing revolt within the party, media reports said on Wednesday. Eagle, a former pensions minister, quit as Labour's top business official on Tuesday, one of more than 20 people to resign from Corbyn's opposition policy team.
