CAIRO — Egyptian intelligence officers met twice over the last three days with the kidnappers of two Americans and an Egyptian tour guide, a senior Egyptian official told CNN on Monday.

“Two of our intelligence officers in charge of Bedouin-related cases visited Germy Abu Masouh on Friday and on Sunday and we have communicated with him by phone,” the official said.

The hostages include Michel Louis, the pastor of a Pentecostal church in Boston; Lisa Alphonse, a parishioner at another American church; and an Egyptian tour guide.

“We saw the hostages, who seemed to be composed, but in a state of shock and fatigue from the grueling heat, especially Michel Louis, who said he had suffered a minor diabetic attack and avoids eating much,” according to the official, who said Louis had been provided with “diabetic pills,” although the intelligence officers did not see the medicine themselves.

Family members had previously said that Louis suffers from diabetes and they weren’t sure if he had his medicine.

Abu Masouh is a member of a prominent Bedouin tribe in the Sinai. He wants Egyptian police to free his uncle, whom Gen. Ahmed Bakr, the head of security in Egypt’s northern Sinai Peninsula, said had been caught in Alexandria, Egypt, with a half-ton of drugs.

The senior Egyptian official said Abu Masouh claims his uncle is a diabetic, too, like Louis, and also has heart problems. Abu Masouh told the Egyptian intelligence officers that the hostages would remain captive as long as his uncle is held. He is supposed to go before a judge in 15 days.

“The Americans would remain for 15 days too, my uncle’s fate will be theirs,” Abu Masouh said, according to the official.

Abu Masouh told Egyptian news outlets that Louis, the pastor of Boston’s Free Pentecostal Church of God, had been allowed to call his wife, who had been on the same bus.

However, the minister’s family has cast doubt on that claim.

“We have spoken to my mother, and my mother has told us that she has not spoken to my father,” Daniel Louis said.

The two Americans and their guide were taken hostage Friday when gunmen boarded their tour bus, which was on its way to Israel, family members said.

Louis offered himself as a hostage after gunmen took the female parishioner, his son, the Rev. Jean Louis, told CNN on Monday.

“Being the leader of the missionary group, my mom said that … he stood up and he just asked that they leave the lady and take him. So this is why there’s two people in addition to the translator detained right now somewhere in Egypt,” Jean Louis said.

The family doesn’t know anything about his father’s condition, or whether he has been able to take medication, he said.

“Everything happened so quickly. … I remember (my mother) clearly telling me on Friday that one of her concerns was that he didn’t have shoes on when they took him off the bus,” he said.

The family is praying for the safety of their Michel Louis and the other kidnapping victims, he said.

“We’re confident not only in the government of the United States and the people that are doing the negotiating. We’re also very confident in the God that we serve. … The scripture says we’re pressed down, but we’re not defeated,” Jean Louis said.

The family was not aware of security concerns about travel across the Sinai, where Americans had been kidnapped and swiftly released in two separate incidents since February, he said.

“If we were aware, I would believe we would use correct judgment not to enter that area,” he said.

Bakr said the situation “is partially the fault of the travel agency,” which he said had not informed police of their route. If it had, “we would have sent a police escort,” he said.

Authorities say the captives are still in the area where they were abducted.

Kidnappings and armed robberies have increased since a popular uprising ousted Egypt’s long-ruling dictator, Hosni Mubarak, last year.

In a message posted on Twitter on Friday, the U.S. Embassy in Cairo said it was “in close touch with Egyptian authorities, who are doing everything they can to bring about safe release of the American tourists.”
