Officials found an unaccompanied 4-year-old boy walking toward the US border, as Biden faces a surge in migrant children trying to enter

• A four-year-old child was found trying to cross the US-Mexico border by himself.
• Mexican officials said he was found walking towards the border near the Rio Grande river.
• An increased number of unaccompanied migrant children have been trying to enter the US.

A four-year-old child was found walking towards the US-Mexico border by himself, officials said Wednesday.

He was found unaccompanied and walking towards the border near the Rio Grande river, said Mexico's National Migration Institute, according to Reuters.

The boy, from Honduras, was rescued by members of the National Migration Institute and the US National Guard, Reuters reported.

He was found near a group of mothers and children also from Honduras, but none of them claimed responsibility for him or said he was their relative, Reuters said.

The boy and the group were taken into what Reuters described as "a local branch of a Mexican authority dedicated to family welfare."

An increased number of unaccompanied children have been arriving at the border after policy changes by President Joe Biden's administration, including measures to reverse controversial Trump-era policies.

The administration says that it doesn't want to turn them back and to dangerous conditions, and doesn't want to send them to someone in the US who has not been properly vetted - leading to crowded detention centers at the border.
