UAE, Bahrain, Qatar and Oman also issue Lebanon travel warnings
Bahrain has called on its citizens to leave Lebanon "for their own safety" hours after Saudi Arabia did the same without giving a reason.
Another Gulf nation, Qatar, meanwhile called on Qataris in Lebanon to “observe caution and vigilance, stay away from the areas that are witnessing the current incidents, and abide by the instructions issued by the competent local authorities.”
The UAE for its part reminded its citizens of the travel ban that has been in effect for years.
Kuwait and Oman have also issued similar travel warnings.
Bahrain's Foreign Ministry said Bahrainis should abide by the government's previous decisions to avoid travel to Lebanon.
The Saudi embassy in Beirut posted a statement late Friday night on X, formerly known as Twitter, calling on its citizens to avoid going to areas where there are "armed conflicts" and also to leave Lebanon quickly.
The decision by the Gulf nations comes after days of fighting in the largest Palestinian refugee camp in Lebanon between members of Palestinian President Mahmoud Abbas' Fatah group and militants of Islamic groups.
The four days of fighting in Ain el-Helweh camp near the southern port city of Sidon has left 13 people dead and dozens wounded.
