A Qassam rocket, which was fired from Gaza toward Israel for the first time in more than a month, fell near Ashkelon on Tuesday, causing no injuries or damage, local police said.
A Fatah-affiliated militant group, Hezbollah Brigades in Palestine, claimed responsibility for the attack, which threatens a fragile four-month ceasefire.
Israel and Hamas-led militants reached a truce agreement on June 19. Under the deal, Hamas agreed to stop firing rockets into Israel, which in turn agreed to reopen its border crossings with the Gaza Strip to allow the supplies of essential goods into the Palestinian territory.
Since then, Gaza militants have occasionally launched rocket attacks on Israeli territory, with Israel closing the border crossings in response.
