Hamas leader in Gaza Yahya Sinwar said the latest war in Gaza was "preparation" for the next war, which will erupt if Israel crosses "the red line" in Jerusalem.
"We are ready to sacrifice what is dear to us for al-Aqsa, Jerusalem and Sheikh Jarrah, " Sinwar said.
"Israel's great intelligence capabilities could not predict Hamas' intentions. We have more than 500km of tunnels and Israel is proud to have destroyed 100km. Hamas' final chord was supposed to include 300 rockets in one go, but out of respect for our brothers in Qatar, we stopped."
