Israel's campaign of air strikes on Gaza's continued for a second night.
The number of casualties is rising and Hamas' retaliation is causing panic inside Israel.
For the first time, rockets fired from Gaza have reached the outskirts of Tel Aviv. Air raid sirens sounded there for the first time in more than 20 years.
Inside Gaza, the bombardment is causing so many injuries that hospital staff face being overwhelmed. And the return fire into Israel is also causing casualties.
