WOODBURY - Sunni militants have captured another strategic city in Iraq, as the United States looks for a way to stop the insurgents' dramatic sweep.

Horrifying images posted on jihadist Internet forums show the mass execution of what are believed to be Iraqi security forces. Several cities are now under the control of an al-Qaida splinter group called ISIS, including the northwestern city of Tal Afar, which fell to militants on Sunday.

Secretary of State John Kerry said during a conference in Washington today that the administration's current focus is on the deteriorating situation in Iraq.

Rep. Peter King (R-Seaford) calls the events of the past week disgraceful. He says ISIS is a group of ruthless terrorists whose next target will probably be Baghdad.

King says that if the group gains a foothold in Iraq, it will put Americans in danger, citing the arrests of three ISIS members in Kentucky three years ago. He says the U.S. must take military action now in an effort to slow down ISIS, but not all Long Island residents agree.

Some say the U.S. is already spread too thin, and should stay out of conflicts as much as possible. Others say that if American troops can work to stabilize the country, then they support U.S. involvement.
