In return, Tehran says it would show flexibility in nuclear negotiations with the US.

This is the latest in the deadliest conflict between longtime enemies Israel and Iran, which have been attacking each other for five straight days.

On Monday Israel escalated strikes on a number of targets. They include Iran's state broadcaster. A live broadcast was interrupted by a missile, and a news anchor had to flee the studio. Israel claimed it was serving as a communications center for Iran's military.
Before dawn on the same day, Iranian missiles had struck Tel Aviv and Haifa, killing several people. Israel launched its air war with a surprise attack last Friday, killing top Iranian military commanders and leader nuclear scientists.
