Kuwait is the latest Arab country to follow in Saudi Arabia's footsteps by urging its citizens already in Lebanon to leave and issuing a travel warning for citizens planning a visit.

Kuwait on Wednesday joined Saudi Arabia, the United Arab Emirates and Bahrain — all member-states of the tight-knit Gulf Cooperation Council — in its call for citizens to avoid travel to Lebanon.

The Kuwait News Agency, which carried the travel advisory by Kuwait's Embassy in Lebanon, gave no details on the nature of the security threat.

The move comes days after Saudi Arabia cut $4 billion in aid to Lebanese security forces in retaliation for Lebanon, which is home to the powerful Iran-backed Hezbollah group, siding with Iran in the Sunni kingdom's spat with the Shiite power.
