Israeli forces are conducting an offensive against Hamas in Gaza by land, sea and air, while Palestinian rockets continue to hit Israel. This map details the latest major developments.
TUESDAY 6 JANUARY
Gaza Strip: Fighting along length of coastal enclave as Israel's ground assault enters its fourth day. Israeli forces reportedly widen their attacks to include Khan Younis in the south, after heavy fighting on the edges of the Deir al-Balah refugee camp in central Gaza.
Gaza City: Heavy fighting between Israeli troops and Palestinian militants on the outskirts of a northern district, where pre-dawn skies were lit up by flares as helicopter gunships pounded militant positions.
Rafah: Reports of an Israeli air raid on the main crossing point between the Gaza Strip and Egypt.
Northern Gaza: At least 18 Palestinians killed. Three Israeli soldiers killed by fire from Israeli tank. At least three Palestinians killed when an Israeli air strike hits a UN school. Others killed as Israeli shell-fire and air strikes hit the Gaza coast and the northern Jabaliya refugee camp.
Israel says at least 130 Palestinian fighters have been killed since the start of the ground offensive on 27 December. Eight Israelis and more than 560 Palestinian civilians have died. The Red Cross describes situation in Gaza as "full-blown" humanitarian crisis.
MONDAY 5 JANUARY
