German Chancellor Olaf Scholz called on Turkey to show restraint toward Greece as tensions between the two countries escalated, Reuters reported.

“The chancellor is of the opinion that, given the current situation, it is necessary for all NATO allies to stand together and refrain from provocations among themselves,” the spokesperson told a regular news conference in Berlin.

“Invading Greek airspace and flying over Greek islands is not okay, it seems counterproductive and against the spirit of the alliance,” added the spokesperson.

Turkey and Greece, NATO allies, have long disagreed on a range of issues such as maritime borders, the extent of their continental shelves and airspace.

Germany is committed to resolving the open questions between Greece and Turkey in private dialogue, and on the basis of international law, said the spokesperson.
