Presidential hopeful Hamdeen Sabbahi and the public figures and campaign staff who accompanied him during his visit to Sinai Wednesday repeatedly received assassination threats by phone on their mobiles and at the campaign headquarters, the campaign said in a statement Thursday.
The campaign said it had contacted authorities to provide security for the group.
Sabbahi refused to cancel the visit as he wanted to celebrate the liberation of Sinai with its people. He did, however, cancel a Sheikh Zuwayed campaign rally at the request of tribal chiefs, the statement said.
State-run Al-Ahram newspaper reported Thursday that Sabbahi and the delegation returned from Sinai at dawn.
Sabbahi held a campaign rally on Wednesday evening in the North Sinai city of Arish, at which he pledged to compensate Sinai for years of neglect and injustice, the paper reported.
He said the time when the people of Sinai were underestimated and their rights overlooked was over, promised his first presidential decision would be to forge a comprehensive reconciliation with the people of Sinai and issue pardons for all Sinai prisoners and detainees.
He also pledged to create a special ministry for the development of Sinai and give people the right to own their land and their homes.
