Background:

Hamas Political Bureau Chairman Ismail Haniyeh (the public face of Hamas) was assassinated in a luxury condo in Tehran, Iran early Wednesday.

The Iranian government directly implicates the U.S. in the attacks.

"The responsibility of the United States, as the strategic ally and main supporter of the Israeli regime in the region, cannot be overlooked in this horrific crime. This act could not have occurred without the authorization and intelligence support of the U.S."

Iran's supreme leader Ayatollah Ali Khamenei said that Israel had "prepared a harsh punishment for itself" by killing "a dear guest in our home."

Less than one day prior, Israeli forces eliminated Hezbollah’s second-in-command, Fuad Shukr, in a strike on the outskirts of Beirut, Lebanon.

The Pentagon has announced that additional military assets will be deployed to the region to bolster force protection for U.S. troops in the region and to defend Israel.
