Four Kassam rockets were fired this morning at the Negev city of Sderot. No one was hurt, but students of a girls' high school near the site of one Kassam landing, as well as residents living in the area, were evacuated for a short while. The rockets were launched from an area in northern Gaza that the IDF encircled on Thursday. City officials say that Sderot has taken some 60 Kassam rockets in the past several months.
