Arab hijackers of a Kuwaiti jet Tuesday brought a 20-year-old woman related to the emir of Kuwait to a microphone and she pleaded with Kuwait to meet the hijackers' demands as the ordeal entered its third week.

"If not, we are all in danger," said Anware Al-Sabah.Anware and her 22-year-old sister, Ibtesam, are the only two women left among the approximately 35 hostages, all thought to be Kuwaitis.

It was the first time either of them has been made to plead for the hijackers' cause.

In a tense but firm voice, Anware said, "We want you to tell our families that my sister and I and all the passengers are well, although our morale is low.

"I hope from my family and government that they will hurry to free the prisoners. If not, we are all in danger. Thank you."

It was the fifth time since the plane landed in Algiers early Wednesday that the hijackers have broadcast appeals from hostages for the Kuwait government to release 17 men convicted on terrorist charges in Kuwait.

The pro-Iranian prisoners were responsible for the 1983 attacks on the U.S. and French embassies in the Persian Gulf sheikdom.

Another of the emir's cousins, Fadel Khaled Al-Sabah, believed suffering from a nervous disorder, broadcast an almost incoherent but similar message Sunday.

Kuwait has refused to meet the demand. There has been no apparent break in the stalemate although Algerian mediators continued their active shuttle between the plane and a high-level Kuwaiti delegation.

This morning contact with the Moslem Shiite hijackers began with a request radioed to the control tower. "Good morning," said one of the hijackers, speaking clearly in English. "We'd like to have water for the plane, someone to clean the toilets and newspapers: five in Arabic and three in French. We also need one medicine, interviaform," a treatment for diarrhea.

A yellow car carried an airport worker to the plane to fill the request.

As the Moslem holy month of Ramadan began on Monday, the hijackers requested copies of the Koran, the Moslem holy book, which were delivered.

During Ramadan, observant Moslems do not eat or drink during daylight hours. At the hijackers' request, a traditional pre-fast meal was delivered to the plane Sunday night for all aboard.

The Kuwait Airways flight from Thailand to Kuwait was hijacked April 5 with 112 people aboard and forced to land in Mashhad, Iran, where 57 eventually were released. On April 8, the jet flew to Larnaca, Cyprus, where two passengers were killed and 13 freed. Since landing in Algiers, one passenger has been freed. The five to eight hijackers are armed with grenades and guns and have threatened to blow up the plane.

A hostage freed on Thursday, 70-year-old Djumaa Abdallah Chatti, flew out of Algeria on Monday night on a Kuwaiti executive jet. Escorted to the plane by four members of the Kuwaiti negotiating delegation, Chatti waved to television cameras before getting on the plane but said nothing.

The hijackers' only direct threat in Algeria was that made Saturday when they asked that the plane be refueled so they could "settle our score" with Kuwait in another country, rather than in "friendly Algeria."

Radio conversations on Monday made no reference to refueling the plane or leaving Algeria.

The official radio reported "new movement that gives a chance for new elements," but did not elaborate.

Algerian officials have been acting as mediators between a Kuwaiti delegation and the gunmen, boarding the plane several times a day for talks.
