Qatar, which provided support for US-led airstrikes in Syria this week, urged the international community to confront the Syrian regime, highlighting pressure by some of Washington's Gulf Arab allies to widen its campaign against Islamic State.
Qatar is among five Arab nations including Saudi Arabia, United Arab Emirates, Jordan and Bahrain that joined in or supported US-led airstrikes against Islamic State targets in Syria beginning late on Monday. US officials said Qatar's role consisted mostly of logistical support.
"The war of genocide being waged and the deliberate displacement carried out by the regime remain the major crime," Qatar's ruler, Emir Sheikh Tamim bin Hamad Al Thani, told the United Nations General Assembly in New York.
The world should work to end "the systematic destruction of Syria" by the Syrian government, he said.
The United States has said its military campaign will not target the Syrian government and instead will focus on the Islamic State, which has seized a third of both Iraq and Syria and seeks to establish a caliphate in the Middle East.
