The State Department says at least nine Americans have been killed by Hamas' strikes on Israel, Fox News has confirmed.
Israeli media also is reporting that at least 800 Israelis have died since Saturday, when the terrorist group first began launching attacks on the country.
"At this time, we can confirm the deaths of nine U.S. citizens," a spokesperson for the U.S. Embassy in Israel told Fox News. "We extend our deepest condolences to the victims and to the families of all those affected.
"We continue to monitor the situation closely and remain in touch with our Israeli partners and the local authorities," the spokesperson added. "We are in touch with the families and providing all appropriate consular assistance."

In an interview on MSNBC, State Department spokesperson Matthew Miller noted that there are also "reports of Americans who are unaccounted for."
"We continue to work to confirm that number and to try to locate those who are missing," he added. "We don't have solid information about either the number or where they might be."

Israeli forces recaptured areas near the Gaza Strip that had been overrun in a Hamas mass-infiltration over the weekend, Reuters reported. The Israeli Defense Force re-established control of communities but isolated clashes remain throughout the country, a military spokesperson said on Monday.
