US will hunt down Kabul airport attack jihadists: Biden

US President Joe Biden has promised to hunt down the jihadists behind an attack in Kabul which killed at least 90 people – including 13 US troops.

Biden warned the US would “not forgive” the perpetrators, reports BBC.

The twin blasts, claimed by a local branch of Islamic State (IS), tore through crowds of men, women and children outside Kabul airport.

They were hoping to join the 100,000 people airlifted out of Afghanistan since it fell to Taliban militants.

There had been repeated warnings that an attack was likely, but it either did not reach or did not deter those waiting.

US troops in control of Kabul international airport have been facilitating the evacuation of foreign nationals and Afghans who had been working with foreign missions.
