The ex-wife of a man who authorities said attacked a synagogue in Michigan told local 911 dispatchers that he was "mentally unstable" before the incident, according to records obtained by Fox News.

41-year-old Ayman Mohamad Ghazali rammed his car into Temple Israel in West Bloomfield on Thursday at 12:19 p.m, according to officials. Ghazali got out of his vehicle and armed security exchanged gunfire with him as he was armed with a rifle.

After he engaged gunfire with security, Ghazali suffered a self-inflicted gunshot wound, according to the FBI.

At 12:21 p.m., Ghazali's ex-wife called 911 and told the operator that "His voice is not stable," referring to her ex-husband, adding that she had just spoken with him, according to records.

"I just want to make sure he’s OK," she said.

Ghazali said that her ex-husband was "mentally unstable due to all his family dying overseas in the war." She said that Ghazali asked her to "send money overseas" before ending the call.
