Israel and Hamas are blaming each other for the collapse of a 3-day ceasefire after just a few hours.
The IDF says one of its soldiers was captured in a Hamas attack in the Southern Gaza Strip.
And Palestinian officials say at least 50 people have been killed during Israeli shelling.
UN official Chris Gunness - whose grief in a TV interview on Wednesday was carried by the world's media - says it's time for the violence to end.
