BEIRUT, Sept. 22 (Xinhua) -- Lebanese Prime Minister Najib Mikati on Friday condemned what he described as an "attack on the American embassy," nearly two days after a gunman fired shots towards the mission's entrance.

"We express our absolute rejection of attacks on diplomatic missions, and we consider the attack on the American embassy an attack on Lebanon's sovereignty and security," a statement released by the Lebanese Council of Ministers quoted Mikati as saying during his meeting with U.S. Ambassador to Lebanon Dorothy Shea.

Mikati said Lebanon's security services had intensified their investigations to unveil the cause of the incident and identify the perpetrator.

For her part, Shea said she appreciated the messages of support from Lebanese political leaders after the incident.

Shea said the embassy's security procedures were solid and work at the embassy continued as usual.

Several shots were fired near the U.S. embassy north of Beirut late on Wednesday, a time coinciding with the 39th anniversary of a deadly bombing attack on the embassy on Sept. 20, 1984.

According to media reports, no one was hurt in Wednesday's incident.
