Foreign nationals told to leave Lebanon amid fears of war

Urgent calls for foreign nationals to leave Lebanon increased on Sunday, with France warning of "a highly volatile" situation as Iran and its allies prepare their response to the recent high-profile killings by Israel.

Lebanon's Hezbollah announced its fighters fired a barrage of rockets at Israel's north overnight.

The Israeli military said 30 projectiles were launched from Lebanon, most of which were intercepted.

France, Canada and Jordan joined other governments in urging their citizens to leave Lebanon. 

"In a highly volatile security context", French nationals were "urgently asked" to avoid travelling to Lebanon, and those already in the country "to make their arrangements now to leave... as soon as possible", the foreign ministry said.

The US and the UK have issued similar warnings.

Several western airlines have suspended flights to the region.

On Sunday, Qatar Airways said that "in light of recent developments in Lebanon", the Doha-Beirut route "will operate exclusively during daylight hours" at least until Monday.
