Seven people have been killed near Kabul airport as thousands tried to flee Taliban-controlled Afghanistan on Saturday.
"Our sincere thoughts are with the families of the seven Afghan civilians who have sadly died in crowds in Kabul," the UK defence ministry said in a statement on Sunday.
"Conditions on the ground remain extremely challenging but we are doing everything we can to manage the situation as safely and securely as possible."
Sky news showed footage showed soldiers standing on a wall attempting to pull the injured from the crowds and spraying people with a hose to stop them from being dehydrated.
