The Wall Street Journal quoted an Israeli official as saying that US President Donald Trump gave Israel the green light to resume attacks on Hamas after the movement refused to release the hostages.

According to the newspaper, the Israeli official indicated on Tuesday that Israel had informed the United States in advance of the operation in the Gaza Strip.

White House spokeswoman Caroline Levitt confirmed in an interview with Fox News that Israel had given advance notice of the attacks.

Levitt warned Hamas and other "enemies of Israel and the United States" in the region that they would "pay a heavy price," saying, "The gates of hell will open," echoing a frequent threat to President Trump.

Trump pressed for the release of all remaining hostages, repeatedly threatening that Hamas would face a return to war if it did not comply. Among the hostages is one living American citizen, Idan Alexander, a dual citizen who was serving in the Israeli military when he was kidnapped by Hamas on October 7, 2023.

According to the newspaper, "Of the 59 hostages remaining in Gaza, Israel believes that up to 24 of them are still alive."

Hamas blamed Israeli Prime Minister Benjamin Netanyahu and his government for endangering the lives of the remaining hostages by canceling the ceasefire.
