Three UNWRA workers were injured Friday morning after a projectile fired from the Gaza Strip into Israel landed near the Karni border crossing and hit a UN building.

Palestinians reported three injured from alleged IDF tank fire in the Sajaiye neighborhood east of Gaza City, according to a report by the Ma'an news agency.

The IDF denied the report, saying that it was not operating in the area and that the three UN workers were injured due to an erroneously fired mortar or rocket.

On Monday, as the Pessah holiday began, a Kassam rocket fired from the Gaza exploded in the Sha'ar Hanegev Regional Council. Warning sirens sounded prior to the rocket landing. No injuries or damage were reported.

Police spokesperson Micky Rosenfeld confirmed that the rocket landed near a kibbutz in the area.

The South has experienced a relative calm for over a week since a tense ceasefire with Hamas was brokered.

Last Friday, two Grad rockets exploded separately in the cities of Ashkelon and Ashdod overnight. No casualties or damages were reported
