Officials said they suspected Mr Injaz was staying illegally in Israel.
They also said that he had been released from prison just days earlier, after serving a jail sentence because of a similar incident at the British Embassy in Israel in 2006.
On both occasions Mr Injaz wielded a plastic gun, and Turkish diplomats said that he was also carrying a knife yesterday.
The stand-off was resolved after Mr Injaz, who had been shot by security guards, was taken to hospital by Israeli paramedics.
Reports in the Turkish media said that the incident has prompted calls for Israel to improve security conditions at the embassy.
