U.S. Secretary of State Marco Rubio on Tuesday said he saw no need to resume major combat operations against Iran because economic restrictions were working so effectively.

Lebanon on Tuesday began new talks with the International Monetary Fund on a bailout to help the country emerge from the worst economic crisis in its history, with progress stalled by its inability to pass banking reforms.

Israel's former military chief Gadi Eisenkot vowed Tuesday to form a government quickly to replace Prime Minister Benjamin Netanyahu as the new parliament prepared to be sworn in.

Iran's Revolutionary Guards said Tuesday that two oil tankers were on fire in the Strait of Hormuz, where the country regularly targets ships that transit without its authorization.

France's foreign minister said Tuesday that Paris ruled out "nothing" to respond to a major cyberattack on hundreds of supermarket fridges in October that it has blamed on Iran.

Iran on Tuesday urged the United States to meet its demands in a plan to reopen the Strait of Hormuz, after President Donald Trump spoke of "positive momentum" to end their eight-month war.

"The conflict with Iran will not be resolved through military means, nor by intensifying sanctions," Foreign Minister Abbas Araghchi told Iran's IRNA news agency.
