The United States’ ambassador to the United Nations says other nations are pledging support for the fight against Islamic State group militants.

But Ambassador Samantha Power on Sunday would not name those countries or detail their level of involvement. She says more than 40 countries have spoken in support of the campaign against Islamic State group fighters, and they will announce their own plans in their own time.

French forces last week joined combat missions. Saudi Arabia has offered to help train moderate anti-Islamic State group fighters.

Power spoke on Sunday morning programs as the U.N. General Assembly prepared a week of high-level meetings, many of them about the growing militants’ threat in Iraq and Syria. President Barack Obama is heading to New York to lead some sessions.
