G7 foreign ministers have voiced support for humanitarian pauses in Gaza but haven't called for a ceasefire.
Their statement follows a meeting in Tokyo.
The US maintains it doesn't believe Israeli forces should re-occupy Gaza, while Israel's Prime Minister says Israel will have overall security responsibility for the strip.

Patman says there's probably not a military solution to a political problem.
