When Antonio Guterres, the UN's new secretary-general, assumes his duties in January - he will inherit, among other challenges, six years of war in Syria.

His predecessor, Ban Ki-moon, failed to engineer an end to the Syrian conflict that has killed an estimated 400,000 people and displaced almost 11 million Syrians - half the country's pre-war population.

Guterres has said that ending the war will be a "top priority", and he is currently in Russia meeting President Vladimir Putin and Foreign Minister Sergey Lavrov, allies of Syrian President Bashar al-Assad.

But the 67-year-old isn't the only new face at the UN.

US President-elect Donald Trump has nominated Nikki Haley as UN ambassador, a former US governor who fought against settling Syrian refugees in her state.

So, what can we expect from these new arrivals? And can we expect a shift in how to end the war?
