European Union (EU) leaders decided on Wednesday to step up sanctions against Iran after Tehran's missile and drone attack on Israel, Reuters reported. In a statement published after a summit in Brussels, EU leaders condemned the Iranian attack, reaffirmed their commitment to Israel's security and called on all sides to prevent more tensions, including in Lebanon. "The European Union will take further restrictive measures against Iran, notably in relation to unmanned aerial vehicles (UAVs) and missiles," the leaders said. On Tuesday, EU top diplomat Josep Borrell said the European Union will prepare to expand its sanctions on Iran in response to Tehran's attack on Israel. "Today, ministers took a strong stance, asking all actors in the region to move away from the abyss, in order not to fall into it," he told reporters. Borrell, the EU's high representative for foreign policy, warned the Middle East would be in "full war" if every development in the current crisis is followed by an escalation.

We anticipate that our allies and partners will soon be following with their own sanctions,” he said in a statement.
