ANKARA, Oct. 23 (Xinhua) -- The Turkish Foreign Ministry on Tuesday summoned the Greek ambassador Petros Mavroidis over territorial waters disputes, state-run Anadolu Agency reported.
The move came after former Greek Foreign Minister Nikos Kotzias, who resigned on Oct. 17, said Greece was ready to extend its territorial waters from six miles to 12 miles in the Ionian Sea.
