At least one Israeli-owned vessel was attacked in the Arabian sea on Feb. 10, a regional defense source said on Friday, in an assault that Iran is assumed to have carried out. The source said drones were likely used and that there were no reports of casualties, Reuters reported. British maritime security company Ambrey Intelligence said unmanned aerial systems had attacked two tankers and one bulk carrier in the Arabian sea and assessed that Tehran had mounted the attack. This came as Israel's Defense Minister Yoav Gallant said on Friday that "all possible means" were on the table to prevent Iran from gaining a nuclear weapon and said the international community had to take action to stop Tehran's proliferation of advanced weapons. Gallant said Iran was expanding its advanced weapons proliferation beyond the region despite an embargo, including talks to sell drones and precision-guided munitions to 50 countries. "When we speak of preventing Iran from gaining a nuclear weapon, we must keep all the possible means – I repeat, all possible means on the table," he said, speaking on the sidelines of the Munich Security Conference.
