In Turkey

Turkish military's "devastating display of power" with its effective domestic drone program against the Syrian regime in Idlib has changed the military equation against Russia, NATO officials said, according to a report.

Greek Ambassador Michael-Christos Diamessis was summoned by the Turkish Foreign Ministry in Ankara on Wednesday, Turkey's Anadolu Agency reported.

Turkish President Recep Tayyip Erdogan on Wednesday appeared to applaud a seemingly deliberate attempt by a Turkish Coast Guard vessel to ram into a Greek Coast Guard patrol off the coast of the Greek island of Kos in the early hours.

Turkey will respond heavily if the cease-fire with Russia is violated in northwestern Syria's Idlib, President Recep Tayyip Erdoğan said on March 11.

If the relevant parties of the Moscow deal violate the deal, Turkey will "never avoid going over them heavier than before," Erdoğan said at the parliamentary group meeting.

However, Russia's attack has compromised Erdogan's attempt to portray Turkey as a regional power. In addition, Arab countries have joined the US policy in Syria and have left Erdogan out in the cold.

The United States has offered to sell Turkey its Patriot missile defence system if Ankara promises not to operate a rival Russian system, Turkish President Tayyip Erdogan said, in what he called a significant softening in Washington's position.

Turkey has a long history of conducting extreme operations with its secret services. The most traumatic of these for us was against the Greek minority in Istanbul in September 1955. On August 21, 2013, it was accused of launching a deadly sarin gas attack on a Damascus suburb, killing hundreds.

"Europe's border doesn't start at the Turkish-Greek border, it starts at Turkey's southern and eastern frontiers," Turkey's Anadolou Agency quoted Foreign Minister Mevlut Cavusoglu as saying on Tuesday.

Anadolou quoted the minister as saying in an interview given to the state-run Turkish agency earlier on Tuesday.

Turkish President Recep Tayyip Erdoğan on March 9 called on NATO members to show their alliance with Turkey "at this critical time."

"NATO is in a critical period in which it should clearly show the alliance's solidarity [with Turkey]," Erdoğan told reporters during a press conference alongside NATO Secretary-General Jens Stoltenberg.

"The lines of communication with Turkey remain open and active," European Commission President Ursula von der Leyen said following a meeting in Brussels on Monday with Turkish President Recep Tayyip Erdogan, which ended without an agreement on the way forward following Turkish moves to encourage thousands of migrants and refugees to push through the Greek border into the European Union.
