Greece has alleged that Turkey's fighter jet formation has entered into its airspace over the Aegean Sea.
The Greek National Defense General Staff (Geetha) said in a statement that Turkey's F-16 fighter aircraft formation entered the Athens Flight Information Region (FIR) at 3:01pm on Tuesday.
The formation entered between the islands of Lesvos and Chios, and then split into four and two aircraft.
One four-F-16 formation flew over Fourni island at 4,000ft, at 3:25pm, while the other two flew over Makronisi and Anthropofagi islands at 8,500ft at 3:27pm, in sequel, and over Anthropofagi island at 8,100ft at 3:29pm.
"The above-mentioned formation exited the Athens FIR, south on Samos island, as follows: the four F-16 at 15:28 and the two F-16 at 3:30pm," the statement added.
The allegation comes a couple of days after Greek Prime Minister Alexis Tsipras accused Turkey of violating Greece's airspace, and creating an 'outrageous' and 'unbelievable' situation over the Aegean Sea.
Tsipras tweeted on Sunday: "We have the most modern aerial weapons systems and yet, on the ground, we can't catch traffickers who drown innocent people."
The tweets were deleted later, reported Al Jazeera.
Last week, Greece claimed that six Turkish planes have breached into its airspace.
Referring to Turkey's downing of Russia's fighter jet in November, Tsipras tweeted: "Fortunately our pilots are not as mercurial as yours against the Russians."
Last month, Turkey shot down Russian Sukhoi Su-24 aircraft for violating its airspace. It claimed that the pilots were warned ten times before firing at them.
