The Taliban* ramped up their military activity amid the US troop withdrawal from Afghanistan, which culminated in militants capturing the capital Kabul without a fight on 15 August.

A Downing Street spokesperson has reportedly rejected allegations that UK Prime Minister Boris Johnson lashed out at US President Joe Biden over America's troop withdrawal from Afghanistan, which was allegedly slammed by London as a "furious" move and "a betrayal".

"These claims are categorically untrue. The prime minister has not criticised President Biden, and they have a very strong working relationship", the spokesperson was quoted by the Daily Mail as saying on Saturday.
