A sharp escalation in border warfare between Israel and Hezbollah in Lebanon has sent Western nations scrambling to update contingency plans for evacuations from the region.

Cyprus, the closest EU member to the Middle East, is a likely hub, having processed around 60,000 people fleeing the Hezbollah-Israel war in 2006.

Neighboring Turkey has offered facilities as well.

Operations-wise, most contingency planning seems to be by sea, enabling movement of larger groups, but that will be defined by the security situation, a source familiar with the process told Reuters.

It takes about 10 hours to Cyprus by sea, or 40 minutes by plane from Beirut.

Here are some details on contingency planning:

Australia

Authorities have made contingency plans that could include evacuation by sea, though it has urged an estimated 15,000 of its citizens in Lebanon to leave while Beirut airport remains open.

Canada

News reports from Canada suggest it will cooperate with Australia in evacuating nationals by sea. The plan involves contracting a commercial vessel to transport 1,000 people out each day, The Toronto Star reported.

United Kingdom

Britain has called for its nationals to leave immediately. It has moved around 700 troops to Cyprus, bolstering its presence in the area where it already has military assets, including two Royal Navy ships. It also has two military bases on the island.

United States

The US has ordered the deployment of dozens of troops to Cyprus to help prepare for scenarios, including an evacuation of Americans from Lebanon.

Portugal

Prime Minister Luis Montenegro on Wednesday advised against travel to Lebanon. The country has a plan to evacuate Portuguese citizens living there in cooperation with partner countries in the EU, he said.
