The Saudi Press Agency also says the kingdom will hand over a protest note to Germany's ambassador to Riyadh.
SPA said the Saudis were referring to Sigmar Gabriel's comments earlier this week during a news conference with his Lebanese counterpart in which he criticised meddling in Lebanon's affairs.
The agency said today that Gabriel's statements were based on "wrong information" and "surprised" the kingdom.
Germany's Foreign Ministry would not comment directly on the development today, but released a statement saying "we are very concerned about the stability of the region and call on all sides to reduce tensions.
