Three rockets landed in Israel's Eshkol region, two hours into a temporary, five-hour cease-fire agreement between Hamas and Israel, according to Israeli newspaper Haaretz.
The newspaper reported that warning sirens were heard in Eshkol Regional Council and Ashkelon areas shortly after noon. It said there were no reported casualties or damage after the attack, The Daily Star reported.
However, Agence France Presse reported that the Israeli army said Eshkol was hit by three mortar bombs fired from Gaza.
The truce, requested by the U.N. to allow humanitarian aid to be distributed in the Gaza Strip, went into effect at 10 a.m.
