The international fight against the self-proclaimed Islamic State in Iraq and Syria has spread to Libya, Tunisia, and Afghanistan. But what about Gaza?
The war-weary isolated strip is controlled by Hamas and is home to nearly two million people. The area presents a fertile recruiting ground for ISIS, though Hamas has started to crack down on Islamic State sympathizers. Failure to control the spread of ISIS could spell trouble for Israel.
Sarah Helm is a journalist covering the Middle East. She recently returned from Gaza, and says another conflict with Israel could present an opening for ISIS to grow in strength.
