Residents of the southern port city of Eilat reported hearing a series of loud explosions at 9:30 p.m. Thursday.
Security forces are checking to determine if these were Grad Katyusha rockets.
Unlike the last time rockets struck the city, no alarm went off this time and no flashes of explosions were seen.
There were no reports of casualties or damage.
Police and military sources confirmed that there were sounds of explosions in the city.
Thus far, no debris of rockets has been found. The IDF has asked the Egyptian military to check for debris on its side of the border.
The last time rockets were fired on Eilat was this past April, when two missiles were sent from the Sinai into the city and warning sirens were activated. One rocket fell in the yard of a house, and the other in a residential area. There was no damage and no casualties.
