A source within Yemen's Ansar Allah movement, widely known as the Houthis, has told Newsweek the group possesses new weapons capable of enforcing a newly announced aerial siege against Israel, whose military said it's on high alert to thwart all emerging threats to the nation's skies following a weekend attack on its busiest airport.

The attack on Ben-Gurion International Airport came hours before top Israeli Cabinet ministers were set to vote on whether to intensify the country's military operations in the Gaza Strip.
