UN Secretary-General Antonio Guterres on Sunday warned of "a rat hole of retaliation" in the wake of U.S. strikes on Iranian nuclear sites.

The U.S. bombing of Iranian nuclear facilities marks a perilous turn in a region that is already reeling, Guterres told an emergency meeting of the UN Security Council.

Iran will defend itself by all means necessary, its foreign minister says, following the US strikes against key sites in Iran's nuclear programme. "Iran continues to defend Iran's territory, sovereignty, security and people by all means necessary," says Iranian diplomatic chief Abbas Araghchi on the sidelines of a meeting of the Organisation of Islamic Cooperation in Istanbul.

Spanish Prime Minister Pedro Sanchez announced a deal with NATO exempting it from the alliance's five-percent of GDP target for defence spending as demanded by US President Donald Trump.
