Lebanon's caretakerPprime Minister Hassan Diab threatened on Saturday to stop performing his duties to pressure politicians to form a new government.

"If seclusion helps with cabinet formation then I am ready to resort to it, although it goes against my convictions for it disrupts the entire state and is detrimental to the Lebanese," Diab said in a speech.

Diab's cabinet resigned on the back of the Aug. 4 Beirut port explosion that devastated swathes of the capital.

Prime minister-designate Saad al-Hariri was nominated in October but has failed to form a new cabinet so far due to political deadlock between him and President Michel Aoun.
