Western nations have bolstered their military presence in the eastern Mediterranean during the conflict in Iran, focusing on the security of Cyprus after an Iranian-made drone hit a British military base on the island on March 2.
Here is a snapshot of military assets that have been sent to the region in addition to those that had been there long-term before the conflict began on February 28.
United States
USS Gerald R Ford, the biggest US aircraft carrier, docked at the Souda base on the Greek island of Crete two weeks ago, before sailing further east with escort ships carrying missiles.
UK
Britain dispatched Wildcat helicopters on March 6, equipped with counter-drone technology.
As speculation mounted in February on US-led strikes on Iran, Britain stationed additional F-35B jets at its base in Cyprus, joining the Typhoon FGR4 aircraft already there.
Britain has said it will also send its destroyer, the HMS Dragon, to Cyprus.
France
France sent its flagship aircraft carrier Charles de Gaulle to the East Mediterranean last week, deploying a dozen naval vessels around it. It was off the Greek island of Crete on Tuesday and was heading to Cyprus. Another French frigate was docked in Souda base on Tuesday.
Germany
German navy frigate FGS Nordrhein-Westfalen arrived in the Cyprus region on March 8.
Greece
Greece has sent its new Belharra frigate, Kimon, and a MEKO 200 frigate called Psara, equipped with the Centauros anti-drone system, to protect the island's airspace.
It also sent four F-16 Viper fighter jets to be stationed in western Cyprus and deployed a Patriot anti-aircraft missile system on the south-eastern Greek island of Karpathos to protect eastern Crete.
Italy
Italy deployed the frigate Martinengo to the region as part of a coordinated mission with EU partners. It was docked in Souda base on Tuesday and was expected to sail to Cyprus in the coming days.
Spain
Spain sent its most advanced warship, the Álvaro de Bazán-class frigate Cristobal Colon, to the eastern Mediterranean. It was docked in Souda Bay on Tuesday.
Netherlands
The Netherlands is preparing to send the air defence frigate HNLMS Evertsen to the region.
