Islamic State terrorist group returns to guerrilla tactics as it loses territory

Islamic State is reverting to the guerrilla-style tactics it employed in its early days to strike targets, including a suicide bombing it claimed in northern Syria this week, as it stands to lose the last sliver of territory it controls.

U.S.-backed forces in Syria on Thursday vowed to escalate military operations against Islamic State and root out its sleeper cells, a day after the attack that killed more than a dozen people, including four Americans.
