The Israeli air force launched airstrikes on the Gaza Strip early on June 16 after militants in the Palestinian territory sent incendiary balloons into southern Israel, security sources and witnesses said.
It is the first major conflict between the two sides since a flare-up in May in which hundreds were killed.
According to Palestinian sources, Israel’s air force targeted at least one site east of the southern Gaza city of Khan Younes.
An AFP photojournalist in Khan Yunis saw the explosions.
The Israeli Defence Force said that in response to the “arson balloons”, its “fighter jets struck military compounds belonging to the Hamas terror organisation”.
The strikes were the first under the new coalition government headed by Naftali Bennett, who took over on June 13 after ousting former prime minister Benjamin Netanyahu.
