Ten Arab states agreed in Jeddah today to rally behind Washington in the fight against the group.
Kerry will meet League chief Nabil al-Arabi "to brief the secretary general on the results of the Jeddah conference", a senior League official said, speaking on condition of anonymity.
Egypt's state news agency MENA confirmed the meeting would take place, and a senior Egyptian official also speaking on condition of anonymity confirmed Kerry would visit, without divulging details about his programme.
The statement came at the conclusion of a meeting in the Saudi Red Sea resort between Kerry and his Arab counterparts.
