Israeli prime minister Benjamin Netanyahu has warned the country is prepared to "significantly expand" its operation in Gaza as "Operation Pillar of Defence" enters its fifth day.
Shelling in Gaza has killed six people today and in Gaza two media buildings were hit with eight Palestinian journalists hurt - leading Israel's president Shimon Peres to deny they were targeting journalists.
Speaking to sky News on Sunday morning, Peres says Israel made "supreme efforts" to avoid hitting civilians.

"Unfortunately, they [Hamas] use their bombs in their mosques to hide their arms, to make them headquarters of shooting. In spite of it, until now I believe almost no civilians were hit.
"We have bombed headquarters where they host journalists as well, it is very hard for us to know, but journalists are not our targets."
According to estimates 52 Palestinians have been killed and more than 400 civilians wounded since Wednesday. Three Israeli civilians were killed earlier in the week and more than 50 have been wounded.
