In a statement Saturday, a State Department official said consular officers have been in contact with the four injured Americans and have been providing appropriate assistance.

In a separate statement, a White House spokeswoman says some staff at the U.S. Embassy in Kenya have been “tragically affected” by the attack. No other information has been released.

The spokeswoman for the White House National Security Council, Caitlin Hayden, says the U.S. has offered its full support to the Kenyan government to bring the perpetrators to justice.
