Conflict in the Middle East has escalated with Israel intercepting missiles fired over them from Iran today.

Sirens are warning tonight across Jerusalem.

Israel first attacked Iran, but Iran has said it is now retaliating.

Crowds of people rallied in Tehran calling for retaliation after the Israeli strikes, and video on CNN shows people celebrating in the streets.

At least 34 people have been injured in Israel.

Iran is threatening to ramp up its nuclear capabilities but Israel says Iran will pay a heavy price for targeting population centres in Israel. The strike yesterday, according to Israel, was aimed at Iran’s nuclear proliferation.

Israel has declared a state of special emergency, which means schools are closed and security measures are at the utmost.

About 100,000 Americans live in Israel
