Mexico's taking control of its oil sector from U.S. and British companies is taught in schools and celebrated every year. The 1938 nationalization is a point of pride for millions of Mexicans including President Andrés Manuel López Obrador.

The popular president hails from the Mexican oil industry's heartland, and 16 years ago he led a fight against energy reforms that were aimed at drawing private investment to the massive state-run oil company, Pemex. This year, the front-runner in the race to replace López Obrador chose the anniversary of Mexico's oil expropriation to announce her energy proposals, which include maintaining large-scale petroleum production by Pemex.

Twenty years after joining the European Union, Poland is still not ready to adopt the euro currency, the finance minister in the pro-European Union government said.

Andrzej Domański, finance minister in the Cabinet of Prime Minister Donald Tusk, said in an interview on TVN24 on Monday that Poland joining the eurozone, the currency union of 20 EU members, is not justified at this time.

The European Union said Tuesday that it's scrutinizing Facebook and Instagram over a range of suspected violations of the bloc's digital rulebook, including not doing enough to protect users from foreign disinformation ahead of EU-wide elections.

The EU's Executive Commission said it's opening formal proceedings into whether parent company Meta Platforms breached the Digital Services Act, a sweeping set of regulations designed to protect internet users and clean up social media platforms.

McDonald's said higher U.S. sales in the first quarter helped it overcome weakness in the Middle East and other markets where consumers have been boycotting the brand.

The Chicago burger giant said its same-store sales – or sales at stores open at least a year -- rose 1.9% worldwide in the January-March period. That was below Wall Street's forecast of a 2.1% increase, according to analysts polled by FactSet.

Nations made progress on a treaty to end plastic pollution as their fourth round of talks finished early Tuesday in Canada.

For the first time in the process, negotiators discussed the text of what is supposed to become a global treaty. Delegates and observers at the Intergovernmental Negotiating Committee on Plastic Pollution called it a welcome sign that talk shifted from ideas to treaty language at this fourth of five scheduled meetings.

If a woman wins Mexico's presidency on June 2, would she rule with gender in mind?

The question has been raised by academics, humans rights organizations and activists ahead of the voting that will likely elect Mexico's first female president for the term 2024-2030.

U.S. Secretary of State Antony Blinken is in Jordan on the second leg of his latest Mideast diplomatic mission to boost aid shipments to Gaza and champion a new proposal for an Israel-Hamas cease-fire that would include the release of hostages held by the militant group.

A day after saying in Saudi Arabia that Israel still needs to do more to get humanitarian assistance into Gaza, and that Israel’s latest cease-fire offer was “extraordinarily generous” to Hamas, Blinken was meeting with Jordan’s King Abdullah II and Foreign Minister Ayman al-Safadi in Amman. Their talks were expected to focus on those issues as well as planning for post-conflict reconstruction and governance of Gaza.

Officials from Hamas have left Cairo after talks with Egyptian officials on a new cease-fire proposal in Gaza, Egypt’s state-owned Al-Qahera News satellite channel said Tuesday.

The channel, which has close ties with Egyptian security agencies, said a Hamas delegation will return to Cairo with a written response to the cease-fire proposal, without saying when.

Israeli officials sound increasingly concerned that the International Criminal Court could issue arrest warrants for the country's leaders more than six months into the Israel-Hamas war.

Prime Minister Benjamin Netanyahu has written in general terms about ICC action against Israeli troops and officials, and Israel's foreign ministry has said it is also tracking reports of pending action.

The United Nations' top court is ruling Tuesday on a request by Nicaragua for judges to order Germany to halt military aid to Israel, arguing that Berlin's support enables acts of genocide and breaches of international humanitarian law in Gaza.

Nicaragua's case is the latest legal bid by a country with historic ties to the Palestinian people to stop Israel's offensive. Late last year, South Africa accused Israel of genocide at the court. The cases come as Israel's allies face growing calls to stop supplying it with weapons, and as some including Germany have grown more critical of the war.
