Striking civilian infrastructure installations during war is illegal, EU chief Antonio Costa said in a social media post, AFP reports.

“Any targeting of civilian infrastructure, namely energy facilities, is illegal and unacceptable,” Costa, the president of the European Council, said.

“This applies to Russia’s war in Ukraine and it applies everywhere. The Iranian civilian population is the main victim of the Iranian regime. It would also be the main victim of a widening of the military campaign,” he said.

“The European Union urges Iran to immediately put an end to its attacks against countries in the region and to allow for the reestablishment of full freedom of navigation through the Strait of Hormuz.”

“After five weeks of war in the Middle East, it is clear that only a diplomatic solution will settle its root causes,” he said.
