   Turkish President Recep Tayyip Erdoğan claimed Tuesday that Greece
   committed a "hostile act" against Turkey and "radar locked" Turkish
   jets with an S-300 air defense system last week, according to Turkish
   media.

   "Greece has challenged NATO and allies by increasing its hostile
   attitude, which started with harassing our airspace and aircraft, to
   the level of S-300 radar lock on," said Erdogan, according to the
   Turkish Directorate of Communications.

   Earlier this week, the Anadolu Agency reported that Turkish jets over
   the Aegean Sea and eastern Mediterranean were harassed by a Greek S-300
   air defence system.
