BrusselscTypeface:> NATO on Tuesday appointed a special representative for the defence alliance’s "southern neighbourhood,” meaning the Middle East, North Africa and the Sahel.

The new envoy is Javier Colomina, who previously served as NATO’s special representative in the Caucasus and Central Asia.

Instability in the southern and eastern Mediterranean poses a security challenge for NATO members in Europe in part by fuelling irregular migration to the bloc.NATO Secretary General Jens Stoltenberg said: "The Middle East, North Africa and the Sahel regions are important to our Alliance. Javier Colomina has extensive experience in dealing with NATO partners. His appointment will further strengthen NATO’s important work in the South.” (DPA)
