United Nations - The latest developments from the annual U.N. gathering of world leaders at which they're tackling major crises like the refugee issue and crises in Syria, Yemen and elsewhere:
President Barack Obama says Nigeria, Tunisia and Malaysia are the newest members of the U.S.-led international coalition to defeat the Islamic State militant group.
Obama made the announcement while leading a special United Nations summit on countering violent extremism.
More than 60 countries, including Arab nations, are working together and launching military airstrikes in an attempt to wipe out IS, which has taken control of large regions in Iraq and Syria.
Obama says defeating the Islamic State will take time, but that the militants ultimately will lose because they have nothing to offer but suffering and death.

Key officials at the United Nations General Assembly are urging the Somalia army and African Union forces to maintain offensive operations against al-Shabab Islamic extremists retake priority areas of the strife-torn country.
A communique issued Tuesday from their meeting on the sidelines of the assembly's annual ministerial meeting called for stepped up support for the military operations which should also aim to degrade al-Shabab's military capabilities, secure main supply routes, and create space to build a peaceful nation.
The meeting — co-chaired by Somalia's president and the heads of the United Nations, the African Union Commission, the Organization of Islamic Cooperation, and the Arab League — "recognized that military efforts alone will not restore security."
They called for a comprehensive approach to counter violent extremism in Somalia and the surrounding region.
The participants expressed alarm at the fragile humanitarian situation in Somalia where almost three million people are dependent on aid to meet their basic needs. At the same time, they commended Somalia for welcoming refugees and returnees from Yemen where a separate conflict is raging.
The U.N. secretary-general has scolded South Sudan's president as the world watches whether the latest shaky peace deal in his country will hold, saying, "I hope you will not betray and disappoint us."
Ban Ki-moon spoke at a high-level meeting on the conflict in the world's youngest country during a U.N. gathering of world leaders.
South Sudan President Salva Kiir, who annoyed the international community by skipping a similar U.N. meeting last year, spoke Tuesday via videoconference from his country.
Kiir said "we have already made considerable progress in implementing the agreement" that he signed with several reservations late last month.
Kiir signed under heavy pressure from the United States, which had championed the country's fight for independence from Sudan.
Kiir accused the opposition of continuing to violate a cease-fire.
