Iraq's prime minister made a rare visit to the country's border with Syria on Wednesday, to support troops and state that Iraqi forces were capable of resisting the Islamic State group. The visit came after militants staged a number of deadly attacks that stoked fears IS may be staging a comeback.

Mustafa al-Kadhimi was in Ninevah province to inspect security measures and boost morale. Concerns of further IS attacks have been growing since over 100 militants just over the border stormed the largest detention facility in Syria's northeast, seeking to liberate suspected IS members.

Russia warned Wednesday it would quickly take "retaliatory measures" if the U.S. and its allies reject its security demands and continue their "aggressive" policies, ratcheting up pressure on the West amid concerns that Moscow is planning to invade Ukraine.

President Joe Biden will host the ruling emir of Qatar at the White House on Monday, a visit that comes as U.S. and European allies are scrambling to put together contingency plans to meet Europe's energy needs should supplies be impacted by Russia further invading Ukraine.

White House press secretary Jen Psaki said Biden and Sheikh Tamim bin Hamad Al Thani planned to discuss Middle East security, ensuring the stability of global energy supplies and the situation in Afghanistan, where humanitarian conditions have deteriorated in the aftermath of the U.S. military withdrawal and Taliban takeover last year.
