Hamas rocket fire targeted Tel Aviv and Al-Quds on Monday.
Roquette alarms have also sounded in certain surrounding cities. US Secretary of State Blinken met Prime Minister Netanyahu and his war cabinet in Tel Aviv on Monday in Tel Aviv.
The meeting was not finished when the alarms rang, said a journalist at the Washington Post.
