According to reports from sources that cannot be verified, Turkish armed forces officials today arrived at the T-4 air base in the Syrian desert and the Palmyra (Palm) military airport in the Homs governorate in central Syria, both of which were recently targeted by Israeli air force attacks.

According to the same sources, citing senior Turkish military officials, S-400 and Hisar-O+ surface-to-air missile batteries will be deployed to these bases alongside long-range drones, as Turkey plans to increase attacks against ISIS and deter further attacks on Syria by Israel.

If Turkey indeed places the S-400 battery as one of the 2 military airfields mentioned above, then Turkey has crossed bright red lines of Israeli defense policy, since the range of these missiles covers a significant part of Israeli territory and constitutes a threat to freedom of flight in Israeli skies, something that Israel cannot agree to and it will have to find a solution to this, either military or diplomatic.
