As EU leaders met with the Turkish PM to finalize a €3 billion ($3.18bn) deal on easing the Syrian refugee crisis, his Greek counterpart criticized Turkey’s “mercurial” pilots for airspace violations that cost billions but in no way help to tackle people-smuggling through borders on the ground.

Alexis Tsipras took to Twitter to point out that it was ironic that while having billions of dollars worth of modern technology in the air, countries can’t resolve the issue of people-smuggling through uncontrolled borders on the ground.
