U.S. oil prices dropped sharply Friday as G7 leaders held urgent talks to coordinate action on lowering fuel prices, after the EU said earlier it would work with the International Energy Agency on releasing further stocks to global markets.

West Texas Intermediate was down 4.0 percent at $89.15 a barrel, having fallen as far as five percent, while the international benchmark Brent crude was down 2.6 percent at $99.63 after several days of trading above the psychological threshold of $100 a barrel.

A wind turbine described by its developer as the world's tallest now rises 365 meters (1,197 feet) above the sparsely populated landscape of eastern Germany, surpassing the height of the Eiffel Tower.

The colossal turbine has been built at an existing wind farm in Lusatia, southeast of Berlin. Once a major center of lignite mining, the region has increasingly turned to renewable energy in recent years. The prototype reached its full height this week and is due to be inaugurated in mid-November.

Americans are deeply frustrated with President Donald Trump's handling of the economy and rising prices, with most panning his performance and blaming his policies as higher costs threaten his party's chances in November.

France's public debt has climbed to a record during the two terms of President Emmanuel Macron, unsettling investors and emerging as a defining issue ahead of next year's presidential election.

President Donald Trump said South Korea plans to invest about $54 billion in a natural gas project in Alaska, an announcement he made in the Oval Office on Wednesday flanked by a Republican senator who has found himself in a tough reelection race in the state.

But while Trump and Alaska Sen. Dan Sullivan — a two-term senator and long-time advocate for the pipeline project — described it as a fait accompli, South Korean officials were more cautious, saying they needed to assess the project's commercial viability before committing to the investment.

Five African heads of state led a ground breaking ceremony Wednesday on a $16-billion oil refinery project in East Africa, following calls for the continent to boost its self-sufficiency in processing raw materials into finished products.

Kenya's President William Ruto hosted his counterparts from Uganda, Ethiopia, Togo, Benin as well as Nigeria's former President Olusegun Obasanjo, shoveling soil at the site to symbolically show construction of the refinery has started.

Medication prices are soaring in Iran and some treatments have become hard to find, leaving patients and their families scrambling as a U.S. blockade and stepped-up sanctions squeeze the country's pharmaceuticals industry.

Some medicines have more than tripled in price, further squeezing Iranians' finances seven months into the country's war with the United States and Israel. Prices for food and other goods have skyrocketed even as unemployment has risen and the currency, which hit a record low this week, has lost half its value.

China on Tuesday rolled out new measures to help boost its economy and sluggish property sector as pressures ramp up ahead of a year-end target for hitting the government's economic growth goal.

European Union nations have spent over an extra 100 billion euros ($113.5 billion) on energy imports since the outbreak of the Iran war, pushing politicians to seek alternatives to fossil fuels as prices skyrocket.

Consumers in some European countries pay nearly 50% more at the pump, equivalent to more than $11 a gallon, following the closure of the Strait of Hormuz, the crucial waterway through which a fifth of the world's traded oil passed in peacetime.
