main entry

Hudaydah port, which is the main entry point for food and other humanitarian aid for millions of Yemenis, has been the target of several Israeli strikes in the past year.

The city is also the main entry port for relief supplies and the UN has warned that this "major escalation" could further complicate aid operations in the country and lead to large-scale civilian casualties.

Gaza's Rafah border crossing, a main entry and exit point for the territory, has reopened after eight months to allow sick and wounded Palestinians to cross over into Egypt to receive medical treatment.

Slovakia had been the main entry point and the country now stands to lose millions of euros in transit fees.

But Ukraine's decision has already caused serious tensions with Slovakia, which is now the main entry point of Russian gas into the EU and earned transit fees from piping the gas on to Austria, Hungary and Italy.
