A grenade was fired at a Health Ministry office in the northern city of Nazareth on Monday night, causing damage but no injuries.
Police said they were summoned to the scene after local residents reported an explosion.
The government office sustained damage, but no injuries were reported, police said.
Police officers opened an investigation and collected evidence from the scene.
