What is the main conflict in By the Rivers of Babylon by Nelson DeMille?

By the Rivers of Babylon, by Nelson DeMille, is the account of a mission of peace gone horribly wrong. A delegation from Israel is hijacked by terrorists set against any form of peace in the Middle East. Crash landing in Babylon, the passengers and crew mount a defense against the group of Arabs that wish to hold them hostage to stop the peace meeting. Escaping in the end, the peace delegation hopes that peace can still be established.
