Anger is growing over an Israeli missile attack on Gaza that killed three children on Monday.

Israeli human rights group B'Tselem has called for an inquiry into the attack, which was defended by Israel's air force commander on the basis that two members of Islamic Jihad were also killed.
Two of the children were stepbrothers, aged 8 and 16. Another boy, 14-year-old Ahmed Sweisi, was also killed in Monday's strike.
B'Tselem called on the military to investigate whether Monday's raid involved the use of "disproportionate" force, "which is defined as a war crime," it said in a statement.

The Israeli air force claimed an ice cream truck carrying two militants had turned onto a crowded street after the missiles were launched and said it was too late to divert them.
The boys' mother said it was too late for explanations or apologies, recalling her anguished search for her boys after the attack.
"I ran to the window when I heard the strike. The window shattered, and I saw a man carrying Mahmoud's lifeless body," said Somaya al-Batsh, mother of eight-year-old Raed and 16-year-old Mahmoud.
"But I couldn't see Raed. I asked everyone, 'Where is Raed? Where is Raed?' A neighbour later told me that he flew through the air from the force of the blast."
"This was a street full of people and children. How can they fire a missile? Who is the terrorist here?" she said bitterly
Some 514 Palestinians age 16 and younger have been killed by Israel since September 2000. During the same period, 97 Israeli children were killed in Palestinian suicide bombings and other attacks.
