The Israeli operation was designed to stop rocket fire from Gaza into Israel, which increased after an Israeli crackdown on Hamas in the West Bank was launched following the 12 June kidnapping and murder of three Israeli teenagers by two Hamas members. Conversely, Hamas's goal was to bring international pressure to bear to lift Israel's blockade of the Gaza Strip, end Israel's offensive, obtain a third party to monitor and guarantee compliance with a ceasefire, release Palestinian prisoners and overcome its political isolation. According to the BBC, in response to rocket fire from the Gaza Strip, Israel launched air raids on Gaza.
