The army announced on Friday that two 107 mm rockets were fired in the Baabda area on Thursday.
The Army Command said in a statement: “Investigations are ongoing to determine the sources of the fire and uncover the perpetrators.”
One of the rockets landed in the garden of the Freiha villa that is located near the Officers' Club.
The second rocket landed near the Khashoqji castle in al-Yarzeh.
No one was injured in the incident.
The Freiha villa is located 100 meters from the secondary entrance of the Baabda presidential palace.
There were reports that a third rocket was fired in the attack, but it has not been confirmed.
Media reports said that it hit an area between Baabda and Bshamoun.
The attack came on the same day that President Michel Suleiman gave a speech on the occasion of Army Day in which he criticized Hizbullah's involvement in the Syrian war in support of President Bashar Assad's forces.
In June, a Grad rocket fired from Ballouneh in Kesrouan district exploded after it hit an electricity line in the Monteverde valley.
The army found a second rocket at the launch site.
In May, two rockets hit Beirut's southern suburbs shortly after Sayyed Hassan Nasrallah made a speech defending his party's fighting in Syria.
