Egypt says the attackers who killed 16 Egyptian soldiers had help from Gaza. In response, Egypt closed its border crossing and shut down hundreds of smuggling tunnels.
The tunnels deliver key goods to Gaza that Israel – which controls its other borders – won't allow in, including construction materials. A tunnel owner who only gave a nickname, Abu Hamam, because of the illegal nature of his business said Tuesday that their price has shot up 40 to 60 percent since the weekend.
A Gaza health official says hundreds of patients are waiting to go to Egypt for medical treatment.
