Saudi Arabia urged its citizens on Monday to avoid travel to Lebanon, state media reported, amid escalating tensions on the border with unrest-swept Syria.
"Due to instability in Lebanon, the foreign ministry warns Saudi citizens from travelling to Lebanon for their safety and that of their families during this period and until further notice," the SPA news agency said.
The warning came hours after a rocket fired towards Syria from Buqaya, in Lebanon's northern Akkar district, wounded two Syrian border police.
The warning also coincides with the tourist season in Lebanon, a major summer destination for nationals from the oil-rich Gulf region.
In May, the United Arab Emirates, Qatar, Bahrain and Kuwait issued similar warnings as clashes linked to the conflict in neighbouring Syria raged in Lebanon's northern city of Tripoli.
Syrian troops have carried out a number of cross-border raids into Lebanon since the outbreak of the revolt against President Bashar al-Assad's rule in March last year, sparking fears of a spillover of the conflict.
