BERLIN (Sputnik) — A diplomatic row erupted late Sunday after Saudi Arabia broke off ties with Iran over attacks on its embassy in Tehran following the execution of a prominent Shiite cleric by Saudis.
"It is all about a new escalation in the relations between Saudi Arabia and Iran, which could undermine all the efforts of the past weeks on [reconciliation in] Syria," Frank-Walter Steinmeier told the Bild newspaper in an interview.
According to Steinmeier, both Tehran and Riyadh should act in a more responsible manner and focus on more important regional issues, such as the Yemeni crisis and fight against Daesh militant group, which is outlawed in many countries, including Russia.
On December 18, the UN Security Council unanimously adopted a resolution outlining a peace process for Syria following talks between 18 ministers of the International Syria Support Group.
Saudi Arabia and Iran are backing the opposing sides in the Syria conflict, with Tehran supporting the Shiite government and Sunni-ruled Riyadh demanding that Syrian President Bashar Assad step down.
