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.
