The United States has temporarily suspended operations at its embassy in Kuwait City, the State Department said in a statement.
The department said no injuries among US personnel have been reported, but emphasised that the safety of Americans abroad remains its top priority.
In its advisory, the State Department urged US citizens currently in Kuwait to leave the country if they can do so safely using commercial or other available transportation.
It also advised those unable to depart to remain indoors and shelter in place until further notice.
