Obama to head UN gathering on countering terrorism
President Barack Obama is chairing a UN gathering of world leaders to discuss countering extremism, a day after he and the leaders of Russia, China and Iran addressed the General Assembly on its 70th anniversary.
At Tuesday's meeting, the United States is rallying support for the fight against groups like the Islamic State, which is attracting foreign fighters who could return to their home countries to launch attacks.
Russia on Wednesday will chair its own meeting on countering extremism as this month's UN Security Council president.
