BEIRUT: The party of Lebanese Prime Minister Saad al-Hariri ? who unexpectedly quit a week ago while in Saudi Arabia ? denounced on Saturday attacks against the kingdom and Iranian intervention in Arab countries.

Hariri?s Future Movement political party said it stands by him and was ?waiting impatiently for his return to Lebanon to handle his national responsibilities in leading this stage?.

Hariri?s shock resignation ? in a broadcast from Riyadh last week ? has plunged Lebanon into crisis and thrust it back into the forefront of regional rivalry between Iran and Saudi Arabia.
