An explosion was heard across northern Tel Aviv in the early hours on Thursday, after a suspected fragmentation grenade was thrown at a residential tower in the upscale Park Tzameret neighborhood, according to Hebrew media reports.

The blast was audible throughout the surrounding area, including Ramat Gan, and reportedly damaged the building's entrance.

“It was loud, but it did not sound like an impact or a grenade,” a local resident told Ynet. “Although it wasn’t close to me, I still heard it clearly.”

No injuries were reported following the explosion.

The Tel Aviv District police stated they have opened an investigation into the incident. The police stated that officers believe the incident has a criminal background.

This is a developing story.
