Desperate families endure perilous journey to reach US border.

Families from various countries are climbing freight trains to reach the US border, enduring hunger, cold, and danger in pursuit of a better life. Some have been waiting for months to enter the US, setting up makeshift tent encampments in border cities. The lifting of pandemic-era immigration restriction Title 42 has renewed their hope, but many still face obstacles such as a lack of appointments with US Customs and Border Protection. Coils of barbed wire recently laid down by the Texas National Guard also pose a challenge for those planning to cross away from border posts.
