Police have determined that a deadly bombing in South Tel Aviv on Sunday night was a failed terrorist attack and that the man carrying the bomb in his backpack who was killed in the blast was a Palestinian from Judea and Samaria.

Authorities are now investigating whether the explosion was deliberate or if the bomb was accidentally triggered before the terrorist reached his target.

A local police commander said earlier Monday that it is “99%” certain that the explosion was a failed terrorist attack, calling it a “miracle” that there were not mass casualties.
