Avichai Adraee, the spokesman of the Israeli army, posted on Twitter that "we have monitored at least one rocket launched from Gaza, but it fell on an open area in the Palestinian territory."
As a result, Adraee alleged that the sirens sounded, but the rocket did not fall on "Israeli territory".
In Gaza, security sources told The New Arab that "at least two missiles were fired at the Israeli settlements in a response to the Israeli massacre in Jenin yesterday."
"Gaza will not let Israel attack the West Bank without punishing it," the source added. "If Israel continues its crimes against our people, the Palestinian resistance will not remain its silent."
Israeli forces killed at least six Palestinians and wounded at least 16 more with live fire during a raid on the Jenin refugee camp in the occupied West Bank on Wednesday.
The Palestinian health ministry identified the victims as Mohammad Wael Ghazawi, Majd Mohammad Huseiniyeh, 26, Tareq Ziyad Natour, 27, Ziad Ameen Zareeni, 29, Moatasem Nasser Sabbagh, 22 and Abdel Fatah Huseein Khrousheh, 49, who Israeli forces accuse of being behind the shooting in Hawara a week ago, that killed two Israeli settlers.
The Ibn Sina hospital and the Jenin public hospital reported that among the injured are severe cases of bullet wounds to the abdomen.
