ATLANTA -- You could say it was a very special delivery for the Atlanta Zoo!
Panda mom Lun-Lun gave birth to twin cubs Saturday.

The cubs arrived less than an hour apart.
They are the first giant panda born in the United States this year and the second set of twins for 19-year-old Lun Lun.
Giant panda cubs are born blind, and almost hairless.

And a little larger than a cell phone.
The zoo says its focus now is making sure they have the best opportunity to success.
