This was peddled on a lot of the Telegram channels tonight but I can't find the actual source. I did find this, however, which seems more measured:
IDF spokesperson Daniel Hagari said in televised remarks: "We will protect the citizens of Israel. This attack will have consequences. We have plans. We will act at the time and place of our choosing."
