Israel is asking the US for precision-guided bombs and additional interceptors for the Iron Dome from, an Israeli military official and a US defense official told CNN.
The Israeli official also said the Israeli military could request more capabilities and weapons, depending on how Israel’s campaign against Hamas plays out.
Also, a National Security Council spokesperson confirmed Sunday that several US citizens were among those killed in the attacks.
Fighters from the Hamas movement killed 700 Israelis and abducted dozens more as they attacked Israeli towns on Saturday.
In response, Israeli air strikes hit housing blocks, tunnels, a mosque and homes of Hamas officials in Gaza on Sunday, killing more than 400 people, including 20 children, in keeping with Prime Minister Benjamin Netanyahu's vow of "mighty vengeance".
