Saudi Arabia has issued a warning against its citizens from travelling to Lebanon and advises Saudi nationals currently in Lebanon to leave, said state-owned media outlet SPA Thursday.

The kingdom has issued several previous warnings about security in Lebanon, but this statement comes at a sensitive time in the two countries’ diplomatic relationship.

Saudi Arabia said it was suspending aid to the Lebanese army last week in response to Lebanon’s failure to condemn attacks by Iranian protesters on Saudi diplomatic missions in January.

The Ministry of Foreign Affairs, headed by prominent political figure Adel Al-Jubeir, recommends that Saudis should only stay in Lebanon if it is absolutely necessary.
