Britain’s foreign minister David Lammy has said he spoke to his Israeli and Iranian counterparts in separate calls, seeking to avoid escalation into a “catastrophic” regional war after Israel struck Iranian military sites, Reuters reports.

“Today I held important calls with Israeli FM (Israel Katz) and Iranian FM (Abbas Araghchi). The UK continues to press for de-escalation and an end to the conflicts in Lebanon and Gaza,” Lammy said in a statement after an Israeli air attack early on Saturday against Iranian targets.

“A regional war would be catastrophic and is in no one’s interests,” he said.
