Qatar cannot validate the number of remaining hostages beyond the 20 to be released by Hamas on Tuesday and Wednesday, he added, in an extension to a truce brokered by the Gulf country alongside Egypt and the United States.
"Our main focus right now is, and our hope, is it reach a sustainable truce that would lead to further negotiations and eventually and end to this situation of violence and to this war," he told journalists in the press conference.
Israeli forces and Hamas fighters appeared to be abiding by a truce for a fifth morning on Tuesday, after the four-day ceasefire was extended at the last minute for at least two days to let more hostages go free.
