Lebanon's Prime Minister Saad Hariri says he will return home "in days" to formally submit his resignation.
Mr Hariri spoke to Future TV from Riyadh, his first public remarks since he announced he was stepping down last week.
"I have resigned. I am going to Lebanon very soon and I will resign in the constitutional manner," he said in the TV interview.
