As the attacks by Iran and Israel continue into their sixth day, here's a look at what we know about the conflict, and if the US will deploy troops.

The Israeli strikes in Iran have killed over 200 people and injured hundreds of others, Iran’s Health Ministry said Sunday. Human rights groups say the numbers are probably much higher. Iranian media reported explosions and heavy air defense fire in the capital of Tehran and explosions in the northwestern city of Tabriz on Tuesday.

Smoke and missiles have lit up the skies in Israel and Iran in a fierce standoff triggered by fears over Tehran’s expanding nuclear program. Since June 13, hundreds of military strikes have been exchanged as the two nations remain locked in a conflict that shows no signs of abating.
