Another private broadcaster, NTV, also reported that one person had been "injured and neutralised" in the incident. No one was immediately available for comment at the embassy.
NTV said the incident happened as two people attempted to enter the embassy. There was no information available about the other person, also a suspected attacker.
An Israeli Foreign Ministry spokesman said a local guard shot and wounded an assailant near the Israeli embassy in Ankara on Wednesday.
"The staff is safe. The attacker was wounded before he reached the embassy," the spokesman said in a text message. "The assailant was shot and wounded by a local security man."
