The families of two Israelis missing in Gaza are complaining over their treatment by government officials, saying their anguish is being ignored.

Friday's remarks came a day after Israeli officials' stunning announcement that two men — Avraham Mengistu, an Israeli of Ethiopian descent, and a Bedouin from Israel's Arab minority whose identity is still under a gag order — are being held captive in the Gaza Strip.

Mengistu's uncle, Tzachi Malasa, told Army Radio that he feels his family is being treated badly "because he's black," referring to his nephew.

A man identified as the missing Bedouin's relative told Israel Radio that "nobody is talking to us, this isn't nice." The relative's identity falls under the same gag order.

There was no immediate response from authorities over the families' complaints.
