Palestinians say young girl in Gaza Strip killed in rocket explosion

A Palestinian medical official says a 3-year-old girl in the Gaza Strip has been accidentally killed by a rocket launched by militants toward Israel.

Ashraf al-Kidra says the girl died when the rocket exploded in the northern Gaza Strip. Three other people were wounded. He said it was not clear whether the rocket was misfired, or whether Israel's "Iron Dome" rocket defense system caused it to explode over Palestinian territory.

The Israeli military says militants fired a total of five rockets at Israel late Tuesday. It says two were shot down by the Iron Dome system, while one fell in an open area and two landed inside Gaza.

Israel responded early Wednesday with a series of airstrikes, saying it targeted five concealed rocket launchers, a weapons-manufacturing facility and a "terror activity" site.
