Iran has targeted the world’s busiest international airport and commercial ships in an escalating campaign against the United States and Israel, aimed at generating enough global economic pain to pressure the U.S. and Israel to end the war that started 12 days ago. The United Nations' most powerful body, the UN, has demanded a halt to Iran's strikes on its Gulf neighbors, threatening global oil supplies. An attack on Iraq's Basra port killed at least one person and halted operations at all the country's oil terminals. The first week of the war with Iran cost the United State $11.3 billion, according to the Pentagon. The International Energy Agency agreed to release 400 million barrels of emergency oil in response to the war's effects on energy markets.
