GAZA CITY, Gaza Strip (AP) -- Israeli warplanes have dropped leaflets on several Gaza City neighborhoods urging people to evacuate their homes immediately.
Tuesday's warnings could signal a new round of heavy airstrikes on residential areas in the Palestinian territory.
The leaflets say "For your safety, you are required to evacuate your residences immediately and move toward central Gaza City" and list areas where people should go.
Palestinian militants have urged residents to ignore the warnings, calling them "psychological warfare."
Egypt's President Mohammed Morsi says a cease-fire ending six days of fighting between Israel and Hamas militants is imminent as top diplomats converge on the region.
Israel has dropped such leaflets previously but never over such a wide area.
Hamas kills suspected collaborators with Israel
GAZA CITY, Gaza Strip (AP) -- Witnesses say masked gunmen have publicly killed six suspected collaborators with Israel at a busy Gaza City intersection.
The Hamas military wing claimed responsibility.
Witnesses said the six men were pulled out of a van Tuesday, forced to lie face down on the street and then shot dead.
Five bodies lay in a pile as a mob stomped and spit on them. A sixth body was tied to a motorcycle and dragged through the streets as people screamed, "Spy! Spy!"
Hamas posted a sign on an electricity pole, naming the six alleged informers.
The public killings came during an Israeli military offensive that has killed more than 120 people, both militants and civilians.
Israel relies on a network of local informants to identify its targets.
