Israel's military has said it will investigate the death of civilians in Gaza after an attack that it originally said targeted a leader of the Islamic Jihad group.
A senior commander of the group was killed by the Israelis on Tuesday.
Islamic Jihad responded by firing rockets into Israel - which then led to retaliatory fire from Israel, killing 34 people in Gaza.
A ceasefire agreed on Thursday remains fragile.
Al Jazeera's Harry Fawcett reports from Gaza.
