“We will all rue the day this decision was made,” said Ms Badenoch.
Israel has targeted Hamas leadership consistently since the war in Gaza began in October 2023
The attack came amid heightened tensions in Jerusalem.
About 20 of the 48 hostages being held by Hamas were believed to still be alive.
IDF said the slain Hamas spokesman led propaganda and psychological terror campaigns.
Amid a war running into its second year, the Israeli government has approved its full military takeover of Gaza in a bid to rescue Israelis held hostage by Hamas.
Israel’s expansion of military action would be in defiance of many other countries’ urging an end to the nearly two-year war in Gaza.
Hamas stated that Israel must cease aerial reconnaissance during the period in which help reaches the hostages.
According to the Hamas-controlled health authority in Gaza, 60,000 Palestinians have been killed in the conflict so far.
Mr Netanyahu condemned Mr Macron’s decision to recognise Palestinian statehood, calling it a reward for terror in the aftermath of the attack on Israel by Hamas.
