Turkish Defence Minister Hulusi Akar's comments came after recent attacks by the Armenian army on the civilian population of Azerbaijan's Ganja city.
Armenia will pay for its terrible attacks on civilians in neighbouring Azerbaijan, Turkey's defence chief has said.
"Sadly, they have attacked the city of Ganja and many other residential areas. This is a clear violation of the ceasefire," said Defence Minister Hulusi Akar, attending the opening ceremony for the school year at the National Defence University on Monday.
"One day they will be held responsible before history and international law for all this," said Akar in the capital Ankara alongside the top brass of the Turkish Armed Forces.
The opening speech of the ceremony had been delivered by Azerbaijan's ambassador to Turkey, Khazar Ibrahim, in what Akar said symbolised the nature and extent of brotherly relations between the two countries.
On recent attacks by the Armenian army on Ganja's civilian population, Akar accused Yerevan of disrespecting humanitarian values and international law.
Relations between the two former Soviet republics have been strained since 1991 when the Armenian military occupied Upper Karabakh, an internationally recognised territory in Azerbaijan.
New clashes erupted on September 27, and since then Armenia has continued attacks on civilians and Azerbaijani forces.
The OSCE Minsk Group — co-chaired by France, Russia, and the US — was formed in 1992 to find a peaceful solution to the conflict, but to no avail. A ceasefire was agreed to in 1994.
Many world powers, including Russia, France, and the US, have urged a new ceasefire. Turkey, meanwhile, has supported Baku's right to self-defence and demanded a withdrawal of Armenia's occupying forces.
Also commenting on the recent departure of Turkey's Oruc Reis seismic research vessel from the Mediterranean Port of Antalya, Akar highlighted that the ship's activities would be coordinated with the Turkish Navy.
Turkey's operations in the eastern Mediterranean comply with international law and regulations, he said, adding, "We have territorial waters in the Aegean and Mediterranean, that have been registered by the UN. The operations we conduct in these areas are of scientific and technical nature and don't constitute a threat to anyone."
"The Turkish Navy will provide escort and protection to the Oruc Reis. We expect our neighbours to avoid provocative actions."
Turkey, which has the longest continental coastline in the eastern Mediterranean, has rejected the maritime boundary claims of Greece and the Greek Cypriot administration in the region, stressing that these excessive claims violate the sovereign rights of both Turkey and the Turkish Cypriots.
Ankara has sent out several drill ships in recent months to explore for energy on its continental shelf, asserting its rights in the region.
Turkish leaders have repeatedly stressed that Ankara is in favour of resolving all outstanding problems in the region through international law, good neighbourly relations, and negotiation.
