The Dutch foreign minister Jaap de Hoop Scheffer is to ask the Saudi ambassador for clarification concerning financial support to radical Muslims. The ambassador is to be summoned following pressure from the government's coalition members. Last week, the interior minister Johan Remkes claimed Saudi Arabia was sending money to radical Islamic groups all over the world, including the Netherlands. It is unclear whether Mr de Hoop Scheffer will speak personally to the ambassador, or when the meeting will take place. The minister leaves for the United States tomorrow on a visit due to last several days.
