The International Committee of the Red Cross is in touch with both Hamas and Israeli authorities about hostages taken by Hamas militants during a deadly incursion, a senior official said on Thursday.
"We are now in contact with Hamas and Israeli officials as part of efforts on this issue," said Fabrizio Carboni, ICRC regional director, who called for their immediate release.
"As a neutral intermediary we stand ready to conduct humanitarian visits; facilitate communication between hostages and family members; and to facilitate any eventual release," he added.
Hamas fighters breached the border fence enclosing the Gaza Strip enclave at the weekend, rampaging through towns and villages and killing 1,200 people while taking scores of hostages, the Israeli military has said.
Roughly 150 people were also abducted by Hamas.
Israeli jets have pounded Gazan targets for days in retribution, and the death toll there has risen to 1,200, Palestinian media reported, citing Gaza's health ministry.
