A ballistic missile attack believed to have been carried out by Houthi rebels killed at least 79 troops and wounded 81 others at a mosque in a Yemeni training camp late Saturday, the AP reports.

The big picture: The training camp is located in the central province of Marib — an oil-rich area approximately 70 miles east of Sanaa, the Houthi-controlled capital. Marib is under the jurisdiction of the Saudi-led coalition, which is supported by the U.S.

Why it matters: The attacks marks a military escalation that followed a rare period of stability in Yemen's long-running civil war, which has caused one of the worst humanitarian crises on the planet.

  • Yemen's internationally-recognized president, Abed Rabbo Mansour Had, condemned the attack as an act of "blatant aggression" that showcases the Houthis' "unwillingness" to find peace.
  • A spokesperson for the Yemeni Armed Forces said the attack would "answered harshly," with coalition forces reporting Sunday that they launched "massive assaults" on Houthi targets northeast of the capital.

Sen. Tim Scott (R-S.C.) told reporters on Wednesday that he believes President Trump "misspoke" when he told the far-right "Proud Boys" group to "stand back and stand by" in response to a question about condemning white supremacy at the first presidential debate.

Catch up quick: Moderator Chris Wallace asked Trump on Tuesday, "Are you willing, tonight, to condemn white supremacists and militia groups and to say that they need to stand down?" Trump asked who specifically he should condemn, and then responded, "Proud Boys, stand back and stand by. But I'll tell you what, somebody's got to do something about antifa and the left."

The Commission on Presidential Debates announced Wednesday that it plans to implement changes to rules for the remaining debates, after Tuesday night's head-to-head between Joe Biden and Donald Trump was practically incoherent for most of the night.

What they are saying: "Last night's debate made clear that additional structure should be added to the format of the remaining debates to ensure a more orderly discussion of the issues," the CPD said in a statement.
