EU High Representative for Foreign Affairs and Security Policy Kaja Kallas has assured that despite the war in Iran and related disruptions to energy supplies, Ukraine remains Europe’s top security priority.

She made the statement in Brussels on Monday after a meeting of the EU Foreign Affairs Council.

"Then we discussed the war on Ukraine. Moscow stands to gain from higher energy prices and the diversion of air defences from Ukraine to the Middle East. Ministers were clear that Ukraine remains a European top security priority and attention for Ukraine will not be allowed to fizzle out," Kallas said.

She said the same drones that strike Kyiv are also striking countries in the Persian Gulf.

"As Ukraine has the best drone defences, we also discussed briefly how we can put these things together: the needs for the Gulf countries, but also the needs of Ukraine and the defence sector and industry," she said.

The EU's top diplomat also pointed out that Russia continues to spread the war to its neighbors.

"Russia keeps spilling the war over to its neighbours. Russia strikes on Ukrainian hydro power plant threatened to contaminate Moldova's water supply. We are supporting Moldova with equipment aid and satellite imagery," Kallas said.

She also commented on the U.S. decision to ease sanctions on Russian oil, stressing that Europe will maintain sanctions and continue reducing dependence on Russian fossil fuels.

"If we want this war to end, Moscow must have less money for the war, not more. Dialling up pressure on Russia's shadow fleet is one of the best tools we have," she said.

In this regard, Kallas praised France, Belgium and Sweden for detaining tankers sailing under false flags.

"It is time for the gloves to come off on Russia's shadow fleet. On the EU side, the adoption of the 20th sanctions package is long overdue. We discussed how to push this forward. The same goes for the EUR 90 billion loan," Kallas said.
