ISIS militants have brought their hardline version of Islam to wide areas of Syria and Iraq, imposing brutal laws and killing people who they deem "unbelievers." Their bloodthirsty advances have sent hundreds of thousands of refugees streaming across the borders into neighboring countries, like Turkey, increasing the risks of instability there. But the recent expansion of U.S. airstrikes against ISIS into Syria, as well as a call by a leader of the extremist group for attacks against Western citizens, has raised questions about how far the militants' reach extends beyond the Middle East. With anti-terrorist raids in Australia, the beheading of a French citizen in Algeria and reports of ISIS sympathizers in Indonesia, here's a look at the countries that could be affected.
