The Moroccan and Egyptian leaders are working hard to unify the Arab nation, currently undergoing very critical conditions, Director of the Rabat Center for Political and Strategic Studies Khaled al Samone said.

Speaking to MENA correspondent here, Samone said the two countries are bound by economic, cultural and strategic ties.

Turning to Yemen, the center director said the expansion of Houthis, backed by Iran, in the country threatens the Gulf region and the Yemeni unity.
