Hamas is leaning toward choosing a relatively unknown successor to political bureau chief Ismail Haniyeh, who was assassinated last week in Tehran, Channel 12 reported on Monday.

According to the report, a majority of the terror group’s leadership supports Muhammad Ismail to replace Haniyeh, at least as a temporary substitute. He is described as a shadowy figure in the organization who has never made any public statements.

Ismail “over the years has become the strongest man in the organization’s economic empire,” said the report. “By virtue of this position, Ismail was involved in directing money transfers from Iran to Hamas and in investments around the world.”
