Israel's plan to expand its Gaza offensive, displace people within the enclave and take control of aid distribution has horrified Gazans who have already suffered multiple displacements and food shortages during 19 months of conflict.

Israel's military has called up tens of thousands of reservists for its planned expanded offensive in Gaza, which an official said entails the "conquest" of the Palestinian territory. But it is not compulsory for reservists to respond to the call-up.

An Israeli plan to seize the Gaza Strip and expand the military operation has alarmed many in the region. Palestinians are exhausted and hopeless, pummeled by 19 months of heavy bombing. Families of Israeli hostages still being held in Gaza are terrified that the possibility of a ceasefire is slipping further away.
