Israel's envoy to the United Nations says that there will be no negotiations about peace, as Tel Aviv attacks Gazan civilians for a third day.

Israel started an 'all-out' war on the Gaza Strip as of Saturday. At least 345 Palestinians have been killed and about 1,550 have been wounded, Palestinian Medics told Press TV on Monday.

When asked about possible peace in the future, Israel's envoy, Gabriela Shalev, told CNN on Monday, "Don't even speak about peace at this moment."

"The hope is that Hamas will understand finally that Israel has the right to defend itself and the duty to protect its citizens," Shalev said without mentioning the hundreds of civilian Palestinians that were killed in Israel's 'blind raids' on civilian infrastructures in the impoverished strip.

Meanwhile, Palestinian peace negotiator Hanan Ashrawi said that she does not accept Israel's argument that it is acting in self-defense.

"Israel is an occupying power," Ashwari said in another interview with CNN on Monday.

"In Gaza, they've been under siege for months now, deprived of the most basic needs. ... And now Israel has decided that if the victims do not lie down and die quietly, it's going to shell them relentlessly from the air," she added.
