“When you take in to account the speeds at which jet planes travel over the sea, it is routine for planes to go in and out of borders,” he was quoted as saying by Anatolia.
“It is something that happens without bad intentions and that happens due to the high speeds.”
However, Turkish President Abdullah Gul said today it was not possible to ignore the fact that Syria had shot down a Turkish fighter jet and said everything that needed to be done following the incident would be done, according to Hurriyet daily news.
“It is not possible to cover something like this up. Whatever needs to be done will be done, without a doubt,” he said.
Gul also said Ankara had been in contact with Damascus and that an operation to search for the plane and missing pilots was still under way.
Turkey has sided with nations such as the US in saying that Syrian President Bashar al-Assad should step down after he responded violently to pro-democracy protests inspired by popular upheavals elsewhere in the Arab world.
Turkey also has set up refugee camps on its border for more than 32,000 Syrians who have fled the fighting.
Ankara has previously hinted the possibility of setting up some kind of humanitarian corridor inside Syria, which would entail military intervention, but has said it would take no such action without UN Security Council approval.
