Twenty-four hours on from the first faltering attempts at a ceasefire, the conflict between Israel and Hamas grinds on to a grimly familiar pattern.
Israel says its warnings are to avoid civilian casualties in planned raids but they'll spread further fear, anger and uncertainty in Gaza where civilians will feel there are no real places of safety now.
Israeli Prime Minister Benjamin Netanyahu now faces a dilemma. There are right-wing members of his cabinet demanding a ground offensive and he doesn't want to look weak in domestic politics. But the risks for him are significant. Ground fighting may cause huge numbers of casualties, alienating Israel's allies, and trap him into a long campaign without a clear exit strategy.
Instinctively he seems to feel that Israelis would prefer to see Hamas diminished and the rocket fire ended through the air campaign. Ground fighting would mean Israeli casualties too.
But if air power doesn't prove decisive, the political pressure for him to go further will grow.
