We're going to wrap our coverage from New York for the day; as the crisis continues to develop overnight, coverage should begin again after a brief break.

• Israel renewed intense air and naval strikes against Palestinian targets, bringing the death toll to 54, including 13 children, and hundreds injured. The Israeli military said it struck more 200 targets on Wednesday alone.

• Hamas and militants fired 60 rockets into Israel today, according to the Israeli military, though there have been no fatalities. Damage to property was reported as rockets landed in and around Dimona, Tel Aviv, Haifa and Jerusalem, and the Iron Dome defense system intercepted 14 rockets.

• Israeli prime minister Benjamin Netanyahu vowed to further intensify attacks on Hamas, and spoke with US secretary of state John Kerry and German chancellor Angela Merkel. The US called for all sides to de-escalate.

• Palestinian president Mahmoud Abbas accused Israel of "genocide" in Gaza, and Hamas leader Khaled Meshaal offered ceasefire conditions, including an end to air strikes and a return to 2012 ceasefire terms.

• Arab nations called an emergency meeting of the UN Security Council, to meet Thursday, with Saudi Arabia's ambassador calling for an immediate end to Israel's "barbaric onslaught" against Palestinians.

• A senior aid worker in Gaza City said the area's already fragile health system threatens to be overwhelmed. "If it [the offensive] continues for more than a few days there will be a real crisis at hospitals," Fikr Shalltoot, director of programmes for Medical Aid for Palestinians, told the Guardian.

• Israel authorized the call-up of up to 40,000 reservists for a possible ground operation."If you ask my humble opinion, a significant operation like this is approaching," said Yuval Steinitz, Israel's intelligence minister.
