Britain has ruled out resettling hundreds of Afghan refugees left stranded after Donald Trump blocked all flights into the US.

More than 1,500 refugees cleared for entry into the US have been left in limbo in Pakistan after they fled the Taliban when they returned to power.

They have pleaded with Britain to open its doors so they can escape from Pakistan where they are facing harassment which they say is linked to rising tensions between Islamabad and the Taliban government in Afghanistan.

Many of the refugees worked closely with US forces or Western agencies during the two-decade war in Afghanistan, leaving them vulnerable to Taliban retribution if they return home.

This crisis is compounded by the worsening conditions for Afghan refugees in Pakistan, where many face exploitation.

Hopes of reaching the US were dashed this week after President Donald Trump suspended the US refugee admissions programs and cancelled all refugee flights into the country as part of a wider crackdown on migration.
