Hamas received weapons and training from Iran, officials say

Militant group that slaughtered hundreds of Israelis received crucial help from Tehran

The Palestinian militants behind the surprise weekend attack on Israel began planning the assault at least a year ago, with key support from Iranian allies who provided military training and logistical help as well as tens of millions of dollars for weapons, current and former Western and Middle Eastern intelligence officials said Monday.

While Iran’s precise role in Saturday’s violence remained unclear, the officials said, the assault reflected Tehran’s years-long ambition to surround Israel with legions of paramilitary fighters armed with increasingly sophisticated weapons systems capable of striking deep inside the Jewish state.

 Was this not detected until now? When did we know first know this?

Hamas, the Gaza-based Palestinian militant organization that led the attack, has historically maintained a degree of independence from Tehran compared with true Iranian proxy groups such as the Lebanese-based Hezbollah. But in recent years, Hamas has benefited from massive infusions of Iranian cash as well as technical help for manufacturing rockets and drones with advanced guidance systems, in addition to training in military tactics — some of which occurred in camps outside Gaza, the officials said.

"In recent YEARS..."? We have known for "YEARS" that Iran was supplying Hamas with "massive" cash, tech help and tactical training?

U.S. and Israeli officials said they have no firm evidence so far that Iran authorized or directly coordinated the attack that killed more than 900 Israelis and wounded thousands. But...officials in Tehran have boasted publicly about the huge sums in military aid provided to Hamas in recent years.
