U.S.-mediated talks in Abu Dhabi have concluded with an agreement on a Russia-Ukraine prisoner exchange, NPR reported. The network said the talks had "wrapped up," and that U.S. negotiators are scheduled to meet Vladimir Putin on Thursday and Volodymyr Zelenskyy on Friday.

The Guardian, reporting in a live blog, said that U.S. envoys are set to meet Putin and Zelenskyy separately. The blog, US envoys to meet Putin and Zelenskyy separately, as it happened, is now closed, according to the outlet's summary of the page.

The same Guardian blog also reported on developments in Italy. According to the outlet, several schools there are being evacuated after receiving bomb threats by email. Citing Rai and Sky TG24, The Guardian said the email was signed by "Mikhail Andropov," the same name used in several hoax bomb alarms against European flights last week.

The reports reviewed for this story do not link the Abu Dhabi talks with the threats in Italy. The summaries also do not give the number of prisoners included in the agreed exchange, the location of the planned meetings with Putin and Zelenskyy, or the number of schools affected.

The Guardian's account and NPR's account come from separate reporting and do not contradict each other on the scheduled meetings. Both describe the U.S. envoys meeting the two leaders separately, with the NPR report specifying Thursday for Putin and Friday for Zelenskyy.
