Iran and the United States have traded threats over critical energy infrastructure in the Middle East, with Iran threatening to retaliate if President Donald Trump follows through on a threat that he could target Iranian power plants. The Iranian government responded by launching a new round of attacks on Israel and issuing its own warning. The threat comes after Iran's missiles hit Dimona, a city 8 miles away from Israel's main nuclear facility, and the nearby city of Arad. Despite three weeks of airstrikes by the United Nations and Israel, over 2,000 people have been killed across the region. Despite these threats, the United Kingdom's military chief of staff has warned of a protracted campaign against Iran.
