Azerbaijani President Ilham Aliyev will not attend Friday's Organization of Turkic States (OTS) summit in Ankara, despite Turkish President Recep Tayyip Erdogan's personal invitation in an October 21 phone call, according to Azerbaijani media cited by Turkish Minute.

The absence follows the departure of Erdogan's chief presidential adviser, Oktay Saral, amid a dispute over Azerbaijan's restrictions on headscarves in schools, Turkish Minute reported.
