Karatachi Yagura recognized Kushina at once.
Kirigakure knew something of the truth behind the Nine-Tails' rampage in Konoha, including how someone had plotted to release the Nine-Tails. Yet Kushina, its Jinchūriki, had not died and had instead sealed the Nine-Tails inside her son. The boy in Kushina Uzumaki's arms was presumably that new Jinchūriki.
