The United Arab Emirates, Qatar and Bahrain on Saturday urged their citizens to avoid travel to Lebanon, where clashes linked to the conflict in neighbouring Syria have left 10 people dead.
The UAE foreign ministry has issued the warning to guarantee the safety of their citizens.
Qatar issued a similar warning due to the “unstable security situation” in Lebanon.
And Bahrain asked its citizens not to travel to Lebanon to ensure their “security and safety” as it urged those already there to “immediately leave or stay away from insecure areas,” the official news agency BNA reported.
Since the outbreak of the uprising against Syrian President Bashar al-Assad in March 2011, Tripoli has become a safe haven for activists and thousands of refugees.
The Alawite sect is an offshoot of Shiite Islam to which Assad belongs and which has controlled Syrian politics for decades.
