Big leveraged buyouts are back, and this year's crop might just be a taste of things to come.

Private-equity firms have announced a record $944.4 billion worth of buyouts in the U.S. so far this year, 2.5 times the volume in the same period last year and more than double that of the previous peak in 2007, according to Dealogic. So far this year, there have been five $10 billion-plus deals in the U.S., equaling the total in all of 2007, though still below the high-water mark of nine in 2006.

Omicron Variant Found on Flights Reveals Gaps in Covid-19 Travel Rules

The probe into two flights from South Africa to the Netherlands, on which more than a dozen people tested positive for the newly discovered Omicron variant, reveal gaps in the patchwork of current travel measures now in place to contain the coronavirus.

Of around 600 passengers on the two flights, 61 tested positive for Covid-19 after being taken off the planes, held for hours in an isolated part of Amsterdam's Schiphol airport and tested. Sunday morning, Dutch health authorities said that at least 13 were confirmed as the Omicron variant, a new strain first identified in southern Africa.

Iran's Nuclear Advances Weigh on Renewed Talks

As negotiators gather in Vienna for talks aimed at reviving an international nuclear agreement with Iran, one big question looms: Has Tehran advanced its nuclear work so much in the past two years that the 2015 deal can no longer be rescued?

Restoring the pact, which placed limits on Iran's nuclear activities in exchange for relief from economic sanctions, is a top foreign-policy goal of the Biden administration. Iran's new president, however, has delayed restarting talks while pressing ahead with nuclear work.

Eurozone Inflation Likely Hit Record High in November

Consumer-price inflation in the eurozone likely hit a record high in November, but many economists think that might mark a peak for now, and therefore don't expect the European Central Bank to raise its key interest rate next year.

As in the U.S., consumer prices in the eurozone have risen faster over recent months than most economists and policy makers had expected. The data have raised questions for investors, businesses and households about the credibility of central bank assertions that this period of high inflation is likely to prove transitory.

Pulling their weapons from hiding, they helped the Taliban rapidly seize control from the inside.

U.K. Looks to Compete on Financial Regulation

London wants to regain the mantle of the world's busiest financial center from New York by overhauling how banks and other financial firms are regulated after Brexit.

WTO Postpones First Meeting in Four Years Amid Covid Variant Concerns

WASHINGTON-The World Trade Organization has decided to postpone a ministerial meeting scheduled to start Tuesday in Geneva, after dozens of nations restricted travel from southern Africa to prevent the transmission of a new coronavirus variant.

The WTO attributed the postponement to newly announced travel restrictions and quarantine requirements in Switzerland and many other European countries, leaving many delegates unable to travel. The group said that the member countries unanimously supported the decision.

In the Land of Dikes, Nature Now Reinforces Flood Defenses

BEVEREN, Belgium-The world's levees are losing the battle against rising seas and overflowing rivers, so experts here want to learn how to fight smarter.

Locals in the coastal regions of northwest Europe, long known as the Low Countries, for centuries have expanded their space for farming and living with earthen barriers that hold back the saltwater and stop freshwater floods. Those triumphs of engineering now face unprecedented assault from oceans and rivers.

Travelers returning home Sunday after the Thanksgiving holiday are encountering busy airports and full flights, but relatively few of the problems that have plagued air travel in recent months.
