Four more hostages held by Hamas in Gaza have been declared dead.
The Israeli army says 85-year-old Amiram Cooper, Haim Perry and Yoram Metzger, both 80, and 51-year-old Israeli-British citizen Nadav Popplewell died together in Khan Younis. Hamas has not yet released their bodies.
Israel's Prime Minister Benjamin Netanyahu said he will not accept a cease-fire in Gaza until all of Israel's conditions are met. The military has carried out more airstrikes in the south of the territory, with no let up in the fighting.
