UN Secretary General Ban Ki-moon has urged an immediate halt to violence in Gaza, saying the Palestinian territory is in a "critical condition".
"In the name of humanity, the violence must stop," he told reporters.
Shortly after he spoke, there were reports of two explosions in Gaza City - one in a children's playground and one near Gaza's main hospital.
Israel launched an offensive against Hamas militants in the territory three weeks ago after a surge in rocket fire.
More than 1,030 Palestinians, mostly civilians, and 43 Israeli soldiers and two Israeli civilians have been killed. A Thai national in Israel has also died.
