US President Joe Biden vowed to keep up air strikes against the Islamic extremist group whose suicide bombing at the Kabul airport killed scores of Afghans and 13 American service members.

Mr Biden also warned another attack was “highly likely” and the State Department called the threat “specific” and “credible” late on Saturday.
