Nawaf Salam, who has been designated as the new Prime Minister of Lebanon, has resigned as a member of the International Court of Justice, said the ICJ on Tuesday.

The top judge at the International Court of Justice Nawaf Salam has been designated Lebanon’s next prime minister in a surprising turnaround for the crisis-ridden country.

The selection of Mr. Salam was seen as a blow to Hezbollah, the Lebanese militant group and political party that has acted as the real power in Lebanon for decades.

Lebanon's Prime Minister-designate Nawaf Salam has called for a new chapter in the country "rooted in justice, security, progress and opportunities" in his maiden speech. However, Mr Salam gave up his position as president of the International Court of Justice and arrived in Beirut on Tuesday morning,

The appointment of Nawaf Salam, the president of the International Court of Justice (ICJ), as prime minister of Lebanon has many Lebanese feeling optimistic. His success in securing enough votes in parliament on Monday caps off a rapid period of political change after Joseph Aoun was elected president last week,

The head of an American organisation focused on hostage releases said on Monday he believes U.S. journalist Austin Tice was still being held in Syria by people loyal to toppled leader Bashar al-Assad.

Nawaf Salam, the president of the International Court of Justice (ICJ) at The Hague, has been named as Lebanon's new prime minister. Two thirds of the 128 members of parliament nominated the 71-year-old judge for the post - reserved for a Sunni Muslim under a sectarian power sharing system - during consultations with newly elected President Joseph Aoun.
