In the last hour I've been getting reports of a Turkish mass incursion into Syria with hundreds of tanks. (Still to be confirmed).
According to the reports the Turkish forces have reached as far as the suburbs of Aleppo, creating a wedge between the mercenary terrorist force and the Syrian army. There has been no sign of Turkish air cover.
The same reports speak of Russian jets having destroyed a Turkish convoy on the outskirts of Aleppo.
