With Israel restricting journalists from accessing Gaza, it has been difficult to obtain images from the conflict there.  The Boston Globe has today published a series of photos they acquired from Palestinian journalists.

For resources on the Arab-Israeli conflict do a subject search in OSCAR for "Arab-Israeli Conflict".  As this is a recent event, you may wish to speak with a librarian at the desk about locating current materials.

There is also a research guide, written by the librarians at Heafey, on Transnational Terrorism.
