The Austin Police Department is holding a news conference to provide more details about a deadly mass shooting over the weekend that left three victims and the suspect dead. The suspect, identified as 53-year-old Ndiaga Diagne, was wearing a shirt with a design similar to the Iranian flag and was under investigation for possible ties to terrorism.

Why it matters

This shooting comes amid heightened tensions between the U.S. and Iran, raising concerns about potential domestic terrorism inspired by geopolitical conflicts. The investigation will examine whether the suspect's ideology and mental health history played a role in the attack.

The details

Ndiaga Diagne, the 53-year-old suspect, was killed in a shootout with police. Authorities found that Diagne had a history of antisemitic, anti-Christian and pro-Iranian posts on social media, and sources say the war in Iran appeared to have been a factor in the attack. Diagne was an immigrant from Senegal who became a U.S. citizen in 2013.

  • The shooting took place shortly after U.S. and Israeli forces launched a massive wave of airstrikes that killed top regime leadership and destroyed Iranian military targets.
