Israel: Ready to 'intensify' fight with Hamas

Israel is ready to escalate its military response to attacks from Gaza, Prime Minister Benjamin Netanyahu said Sunday after scores of rockets struck Israel overnight.

"The world must understand that Israel will not sit idly against attempts to harm us. We are ready to intensify the reaction," Netanyahu said.

Israeli forces are already striking at terror groups in Gaza behind the attacks, he said.

The Palestinian death toll in the latest violence has risen to six, according to the Palestinian news agency WAFA. Also, more than 30 Palestinians have been wounded, with 10 of them in critical condition, according to the report.

Initial reports indicate four Israeli civilians were wounded by the rocket attacks, according to Israeli military spokeswoman Avital Leibovich. Four Israeli soldiers were wounded Saturday, according to the military.

"Due to continuous rocket attacks" from Gaza, school was canceled Sunday in some Israeli communities, Leibovich tweeted. She added the hashtag: "#terror."

Hamas spokesman Fawzi Barhoum warned against escalating the violence and targeting civilians, saying "we cannot sit idle towards it. An end should be put to it."
