Several countries have urged their nationals to leave Lebanon, as fears grow of a wider conflict in the Middle East, Paralel.Az reports citing BBC.

Iran has vowed “severe” retaliation against Israel, which it blames for the death of Hamas political chief Ismail Haniyeh in Tehran on Wednesday. Israel has not commented.

His assassination came hours after Israel killed Hezbollah senior commander Fuad Shukr in Beirut.

Western officials fear that Hezbollah, an Iran-backed militia and political movement based in Lebanon, could play a key role in any such retaliation, which in turn could spark a serious Israeli response.

Diplomatic efforts by the US and other Western countries continue to try to de-escalate tensions across the region.

A growing number of flights have been cancelled or suspended at the country’s only commercial airport in Beirut.

The US, the UK, Australia, France, Canada, South Korea, Saudi Arabia, Japan, Türkiye and Jordan are among the countries to have urged their citizens to leave Lebanon as soon as possible.

Fears of an escalation of hostilities that could engulf Lebanon are at their highest since Hezbollah stepped up its attacks on Israel, a day after the deadly Hamas attacks on southern Israel on 7 October, in support for Palestinians in Gaza.

Most of the violence has been contained to border areas, with both sides indicating not being interested in a wider conflict.

Hezbollah, however, has vowed to respond to Shukr’s assassination, which happened in Dahiyeh, the group’s stronghold in Beirut’s southern suburbs.
