Tens of thousands of people have joined nationwide protests across the US over the Trump administration's hardline immigration policies.

More than 630 events were planned, with protesters calling for migrant families split at the US border to be reunited.

About 2,000 children remain separated from their parents and concerns remain that records were not kept linking parents and children.

The original Trump administration "zero tolerance" policy required authorities to arrest and detain anyone crossing the Mexico‑US border illegally. That meant separating children from their parents and holding them separately.
