Canadian Prime Minister Justin Trudeau announced Friday that the government would immediately ban the use and trade of roughly 1,500 different kinds of assault-style weapons, including the AR-15 variant that has been used in many U.S. mass shootings, reports The Globe and Mail.

Why it matters: 22 people died during a rampage in Nova Scotia last month — and 13 were killed by gunfire, per CNN, making it one of the deadliest mass shootings in Canadian history. While authorities have not revealed the weapons used during that incident, the ban does include them as well.

  • The order doesn't outright ban the ownership of such weapons, though Trudeau said it was "closing the market for military grade assault weapons in Canada."
  • It has a two-year amnesty period for current owners of the weapons, as well as a compensation program that will require parliamentary approval.
  • For now, the weapons can only be transported for export, return or deactivation, though there are limited circumstances where they can also be used to hunt.

What they're saying: "Canadians need more than thoughts and prayers. ... There is no use —and no place — for such weapons in Canada," Trudeau said.

President Trump signed an executive order on Monday that would impose sanctions on any person or entity that contributes to the supply, sale, or transfer of conventional arms to or from Iran or is engaged in providing training and financial support related to those weapons.

Why it matters: The executive order is the first step by the Trump administration to put teeth into its claim that international sanctions on Iran were restored over the weekend, one month after the U.S. initiated the "snapback" process under a United Nations Security Council resolution.

CDC says it mistakenly published guidance about COVID-19 spreading through air

The CDC has removed new guidance that acknowledged airborne transmission of the coronavirus, posting in a note on its website that the guidance was only a draft and had been published in error.

Why it matters: The initial update — which was little noticed until a CNN story was published Sunday — had come months after scientists pushed for the agency to acknowledge the disease was transmissible through the air. The CDC previously said that close person-to-person contact was the bigger concern, and the language has been changed back to erase the warning about airborne transmission.
