German Foreign Minister Johann Wadephul said Monday it will be important for the U.S. and Israel to define “when they consider the military aims of their deployment to have been reached,” The Associated Press reports.

Before meeting EU colleagues in Brussels, Wadephul said he told his U.S. and Israeli counterparts “we need more clarity here.”

He also said the Iranian government poses a significant danger to the region, the freedom of shipping and the global economy and “this danger definitely must not continue.”

Wadephul said without elaborating that he would back sanctions against those responsible for blocking the Strait of Hormuz.

He said once there is clarity on the U.S.-Israeli aims it will be time for a phase when “a security architecture for this whole region” is defined, which will entail speaking to Iran.
