Several countries are urging their citizens to avoid travel to Lebanon.

Since last Saturday, at least 13 people have been killed as fighting continues on Lebanon’s southern border with Israel where Hezbollah holds sway. In recent days, there has been a “significant escalation” by Hezbollah in its skirmishes with Israel, Israel Defense Forces spokesperson Lt. Col. Jonathan Conricus told CNN's John Vause on Thursday.

“We've updated our travel advice for Lebanon and now advise do not travel due to the volatile security situation and the risk of the security situation deteriorating further,” the advisory read. “Terrorist attacks could occur anytime and anywhere, including in Beirut."

The advisory added that in a “deteriorating security situation,” the government’s ability to assist citizens to depart Lebanon will be “very limited.”

"You are advised against all travel to the whole of Lebanon. If you are currently in Lebanon, we encourage you to leave now while commercial options remain available," the FCDO said in its latest update.

US: On Tuesday, the US Department of State issued a travel advisory raising Lebanon’s status to Level 4: Do Not Travel, citing “the unpredictable security situation related to rocket, missile, and artillery exchanges between Israel and Hizballah or other armed militant factions.”

The advisory came a day before Pro-Palestinian demonstrators had skirmishes with police near the US Embassy in Awkar, which is just north of the capital Beirut.

Canada issued the travel notice Monday night, advising citizens the security situation in Lebanon was "volatile" and could deteriorate without warning. Source: CNN News
