NNA said that two guards -- Butros Mikhael Iskandar and Bakhos Ibrahim Jerjes -- were maimed in the incident that erupted at 5:00 am with two drunken occupants of a vehicle.
The two men were speeding near the mansion when one of the guards stopped them asking about their inappropriate behavior, the agency said. One of the drunk men hit the guard while the other shot at him, which forced the guards to open fire at them.
One of the occupants identified as Naim al-Doueihy was also injured, NNA said.
It added that the army immediately intervened and cordoned off the area.
Marada movement leader MP Suleiman Franjieh said in a statement later Sunday that the shooting near his grandfather's house should not be exaggerated and that the incident would not affect the tourism season in Ehden.

Najib Miqati telephoned Franjieh and followed with Interior Minister Marwan Charbel the investigation into the Ehden incident.Later on Sunday, al-Doueihy family issued a statement following a meeting at the residence of lawyer Youssef Bahaa al-Doueihy in Ehden.
The conferees accused "some people of distorting the facts through some media outlets," noting that "the incident started when armed cut-throats positioned on the public road opened fire on the passing cars."
"What happened was not aimed at attacking a certain politician, as some have tried to portray the incident and are trying to exploit it," al-Doueihy family said in the statement.
"We hope security and judicial institutes will not apply double standards ... especially that some consider the defense ministry to be a farm, and we stress that we will abide by the law as much as those in charge of the case will abide by objectivity and neutrality," the family added.
"We remind them that their regional sponsor had never managed to scare us, even during the epitome of its occupation of Leb ... We will not tolerate any attack on people's dignities," it warned.
