A rocket landed on Sunday at the Egyptian side of Rafah crossing at the border with the Gaza Strip, causing damage to an Egyptian building, the official MENA news agency reported.
The rocket knocked down a wall of the building at the border crossing, said MENA, without report of casualties.
According to the report, an expert technical committee rushed to the scene of the accident and was trying to find out where the rocket was made and who had launched it.
Israeli forces were carrying out air raids near Rafah crossing in southern Gaza Strip.
The Rafah terminal, Gaza's only door to the outside world bypassing Israel, has been kept closed since last June when Hamas militants routed rival Fatah's security forces and seized the coast strip.
On Jan. 23, Hamas militants blew up the border fence between Gaza and Egypt, allowing hundreds of thousands of Gazans to pour into Egyptian border towns to stock up on food and fuel.
