Barbados stopped pledging allegiance to Queen Elizabeth II on Tuesday as it shed another vestige of its colonial past and became a republic for the first time in history.

China, which is increasingly flexing its muscles around the world, is one of the biggest threats to Britain and its allies, and a "miscalculation" by Beijing could lead to war, the head of the U.K.'s foreign intelligence agency said Tuesday.

Syria has hosted the first international basketball tournament on its soil in at least two decades, bringing an Asia region World Cup qualifying game to a packed stadium in the capital Damascus.

The emergence of the new omicron variant and the world's desperate and likely futile attempts to keep it at bay are reminders of what scientists have warned for months: The coronavirus will thrive as long as vast parts of the world lack vaccines.

The hoarding of limited COVID-19 shots by rich countries — creating virtual vaccine deserts in many poorer ones — doesn't just mean risk for the parts of the world seeing shortages; it threatens the entire globe.

Iran struck a maximalist tone Tuesday after just one day of restarted talks in Vienna over its tattered nuclear deal, suggesting everything discussed in previous rounds of diplomacy could be renegotiated.

Iranian state media reported the comments by Ali Bagheri, Iran's top nuclear negotiator, and Mohammed Eslami, the country's civilian nuclear chief. It remained unclear, however, whether this represented an opening gambit by Iran's new hard-line president or signaled serious trouble for those hoping to restore the 2015 deal that saw Tehran strictly limit its enrichment of uranium in exchange for the lifting of economic sanctions.

Can the landmark 2015 nuclear deal between Iran and world powers be restored? As Iran and six global powers gather in Vienna Monday to discuss the tattered treaty, the answer appears to be no.

Since then-President Donald Trump withdrew from the agreement in 2018, Iran has raced forward with its nuclear program, making it all but impossible to simply turn back the clock. The election of a hard-line leader in Iran, coupled with a U.S. administration seen as weak in the region, have further dampened prospects for a breakthrough.
