EU chief Ursula von der Leyen called Monday for “united action” on border security after a migrant rush on Spain’s North African enclave of Ceuta triggered a public spat between Madrid and several European partners. “From this incident, it is clear that we must do more to further strengthen our borders at critical points,” von der Leyen wrote in a letter to Spanish Prime Minister Pedro Sanchez seen by AFP.

The videoconference set for Tuesday will be a chance to draw “lessons” from the Ceuta episode, von der Leyen said, warning the challenges of illegal immigration require “a common European response, united action and solidarity”. Framing Tuesday’s meeting as a “first step,” von der Leyen said she expected leaders would take up the issue at their next summit, currently planned for October.
