Gaza war frays Egypt-Israel pact

Egypt and Israel have officially been at peace for the last 40 years, thanks to a treaty President Jimmy Carter brokered at Camp David in 1978.

The majority is adamant about a ceasefire, but a small group of families also formed a group opposing negotiations with Hamas. Plus, "doping Olympics" gets its first athlete.
