Palestinians fired a mortar that landed north of the Karni crossing Sunday evening, causing no damage to property and wounding none, Army Radio reported.
IDF artillery units responded by firing six salvos towards northern Gaza fields from where the mortar was suspected to have been fired.
IDF sources said that the artillery barrage would last into the night, "because the Palestinians have to understand that we will not accept high-trajectory shooting."
"Our response will be exaggerated and disproportionate," said another IDF source, adding that if the mortar attacks continue the IDF response would grow even stronger.
