Blinken says immigration challenges facing US at the southern border are 'beyond anything that anyone has seen before'

US Secretary of State Antony Blinken told CNN that the immigration challenges facing the Biden administration along the southern border are "beyond anything that anyone has seen before," and that the issue will be a key focus of a summit of regional leaders taking place this week in Los Angeles.

"We're dealing with a challenge that, for a whole variety of reasons, is beyond anything that anyone has seen before, which is exactly why the approach that we're taking, including here at the summit, is so important," Blinken told CNN en Español's Juan Carlos López during an interview conducted on Tuesday at the Summit of the Americas in Los Angeles.

He continued: "And that is an approach of shared responsibility where everyone in the hemisphere who is affected by irregular migration in particular, migration more generally, that is countries of origin, transit countries, countries of destination, come together to take shared responsibility for managing this in a safe, humane and orderly way."
