Saudi Arabia alleged Thursday that the United Arab Emirates smuggled a separatist leader in Yemen wanted for treason out of the country and flew him to Abu Dhabi.

President Donald Trump's administration on Wednesday sought to assert its control over Venezuelan oil, seizing a pair of sanctioned tankers transporting petroleum and announcing plans to relax some sanctions so the U.S. can oversee the sale of Venezuela's petroleum worldwide.

Trump's administration intends to control the distribution of Venezuela's oil products globally following its ouster of President Nicolás Maduro in a surprise nighttime raid. Besides the United States enforcing an existing oil embargo, the Energy Department says the "only oil transported in and out of Venezuela" will be through approved channels consistent with U.S. law and national security interests.

The Senate is expected to vote on a resolution Thursday that would limit President Donald Trump's ability to conduct further attacks against Venezuela, setting up a test for his expanding ambitions in the Western Hemisphere.

The war powers resolution would require Trump to get congressional approval before striking Venezuela again, and it comes after the U.S. military seized the president of the South American country, Nicolás Maduro, in a surprise nighttime raid and as Trump's administration is seeking to control Venezuela's oil resources and its government.

Denmark has welcomed a meeting with the U.S. next week to discuss President Donald Trump's renewed call for the strategic, mineral-rich Arctic island of Greenland to come under American control.

More artificial intelligence is being implanted into Gmail as Google tries to turn the world's most popular email service into a personal assistant that can improve writing, summarize far-flung information buried in inboxes and deliver daily to-do lists.

Israel's Foreign Ministry said Thursday that Hezbollah is "rearming faster than it is being disarmed," showing a map of alleged Hezbollah compounds, launch sites, and underground networks south of the Litani River.

Yemen is threatening to fracture even further, exposing a growing rift between Middle East powers Saudi Arabia and the United Arab Emirates. The latest friction is among members of the Saudi-led coalition based in Yemen's south that for years has been fighting Iranian-backed Houthi rebels based in the north.
