"There is a strong possibility of new attacks on some of our targets in Syria and Iraq," a US official said.


 A US official, who did not want to be named, told NBC News:  The damage caused by the attack has not yet been fully revealed. If we find that some of our targets were not completely destroyed, we will bombard them again.

 
 "If the results are not like what we expected, new orders will be issued for new attacks," he said.


 "It's too early to talk about the impact of the attacks on the US-Iraq talks on the withdrawal of US troops," he said.
