A senior U.S. official says the number of troops currently under discussion would be fewer than 300, but there has been no final decision yet by Pentagon leaders.
The talks come as American fighter jets and drones conducted nearly a dozen airstrikes in Iraq since Tuesday when Islamic State militants threatened to kill a second American captive in retribution for any continued attacks.
A U.S. official says the strikes came in the hours after militants released a gruesome video Tuesday showing U.S. journalist James Foley being beheaded.
