The Israeli army has killed a Palestinian youth in the northern Gaza Strip and wounded at least three other people.
The army says it targeted a man who was collecting a rocket launcher from an area used to fire rockets at Israel recently.
Palestinian medical sources say the Israeli strike killed a teenager.
The Israeli military began an offensive in Gaza after militants kidnapped an Israeli soldier in June. More than 200 Palestinians have been killed in the offensive.
On Sunday, Palestinian Prime Minister Ismail Haniyeh said his Hamas-led government will not recognize Israel.
He said an Arab peace plan for the region is problematic because it requires Palestinians to recognize Israel in exchange for an Israeli pullout from Palestinian territories.
He spoke after a week of deadly political infighting between Hamas and the rival Fatah party of President Mahmoud Abbas.
