Israeli airstrikes in Gaza resulted in the death of sixteen Palestinians. Eleven more Palestinians died near food distribution centers. Witnesses repo

Israel's airstrikes have severely weakened Iran's nuclear capabilities and military leadership, leaving Tehran with limited retaliatory options.

The Israeli military on Sunday released video it said showed the underground rooms where they found the body of Hamas leader Mohammed Sinwar who is believed to have died in tunnels under a Gaza hospital last month.

Israel and Iran opened a new chapter in their long history of conflict when Israel launched a major attack with strikes early Friday that set off explosions in the Iranian capital of Tehran.

For years, Israel and Iran engaged in a shadow war, a series of mostly quiet, often deniable attacks, with Iran frequently operating through allied proxy groups.

He was the younger brother of Yahya Sinwar, the former Hamas leader killed by Israel last year. Hamas did not immediately respond to the claim of his death.

Syrian Observatory for Human Rights reports one dead and two others wounded in the Israeli attack on a vehicle.

The IDF has confirmed that senior Hamas leader Mohammed Sinwar was killed in a May 13 airstrike targeting an underground command center beneath a hospital in Khan Younis, Gaza. Sinwar had succeeded his brother Yahya Sinwar as head of Hamas after Yahya and Mohammed Deif were killed last year.

It says that dozens of Israeli Air Force jets "completed the first stage" of the attack, which includes "strikes on dozens of military targets, including nuclear targets in different areas of Iran". It says that weapons of mass destruction in the hands of Iran are an "existential threat" to Israel "and to the wider world".
