JERUSALEM, Jan 28 (Reuters) - Talks held on Sunday initiated by Qatar, the United States and Egypt to broker a hostage deal between Israel and Hamas were "constructive" but meaningful gaps remain, a statement from the Israeli prime minister's office said.

The statement said the summit was held in Europe and that the parties would continue to hold discussions during additional meetings planned for later this week.

"There are still significant gaps in which the parties will continue to discuss this week in additional mutual meetings," the statement said. (Reporting by Emily Rose. Editing by Jane Merriman)
