Ammon News - Hamas leader Ismail Haniyeh was assassinated in the early hours of the morning in Iran, the Palestinian militant group said on Wednesday, drawing fears of wider escalation in a region shaken by Israel's war in Gaza and a worsening conflict in Lebanon.

Iran's Revolutionary Guards confirmed the death of Haniyeh, hours after he attended a swearing in ceremony for the country's new president, and said it was investigating.

There was no immediate comment from Israel. The Israeli military said it was conducting a situational assessment but had not issued any new security guidelines for civilians.

U.S. Defense Secretary Lloyd Austin said Washington would work to try to ease tensions but said the United States would help defend Israel if it were attacked.
