Two police officers and a civilian were killed Tuesday during a shootout in the Belgian city of Liege, according to Sputnik.

According to a local TV station, an armed man shot the two police officers at the Cafe des Augustins on the Boulevard d'Avroy, located in the city center. He then fled and tried to take a housekeeper hostage at Waha High School. Police responding to the incident managed to subdue the gunman, but during the shooting, a passerby was also killed. Students were unarmed and did not come into contact with the gunman, who has since been "neutralized".

Here's what we know so far:

4 dead in total

Other photos circulating online showed first responders arriving at the scene. Witnesses said they heard many shots ring out during the shootout. Eventually, a security perimeter was established and ambulances dispatched to the scene.

Liege is located in eastern Belgium near the border with Germany.

Belgium's anti-terror crisis center has been monitoring the situation, officials said. Liege was also the site of a 2011 shooting where a gunman killed four people before turning the gun on himself.

Belgium has been on high alert since a Brussels-based Islamic State cell helped carry out the Paris attacks in 2015 that killed 130 people at the Bataclan theater. Another attack in Brussels in 2016 left 32 dead. Today's attack unfolded during Ramadan, the Islamic holy month.
