Syria topping agenda at UN meetings
World leaders will be in New York this week for the General Assembly of the United nations. Topping the agenda will be the crisis in Syria and Iran's nuclear plans.
Egypt's President Mohamed Morsi, on his first official trip to the United States, travelled to the city on Sunday for the 67th session of the UN General Assembly.
Iran's President Mahmoud Ahmadinejad is also in town and will address the General Assembly on Wednesday.
David Common, reporting from New York, says security has been tightened around UN buildings for what New Yorkers are calling UN Week.
