WASHINGTON (AP) — Cities in the United States and Western Europe are being eyed as Islamic State militants’ future targets and President Barack Obama needs to take action, U.S. lawmakers say.

Without offering specifics on any threats or suggestions on how to confront them, the leaders of the Senate and House intelligence committees on Sunday prodded the White House to work to prevent the Islamic State extremists from launching attacks on U.S. soil. The bipartisan pair of lawmakers shared a dire warning about the Islamic State group, which now has control of vast swaths of Syria and Iraq, has killed civilians from that region and beheaded American journalist James Foley.
