AGENCIES: World leaders have gathered in New York City for the 74th session of the United Nations General Assembly (UNGA).

The meeting comes amid simmering tension in the Middle East over recent attacks on Saudi Arabian oil facilities, which the United States blames on Iran, allegations Tehran denies.

UNGA also comes just days after millions of young activists and their supporters marched in thousands of cities worldwide to demand greater action on climate change.

The general debate is taking place from September 24 to September 30, with dozens of world leaders scheduled to address the General Assembly.
