U.S. border agents have tracked the latest exodus from Honduras this week.

The "Sardines" grassroots movement protesting against the populism of far-right Italian leader Matteo Salvini staged a mass rally in the northern city of Bologna on Sunday ahead of a regional vote that could shake up national politics.

Moscow protest over Putin's political shake-up fails to gain traction

Over 1,000 people marched through Moscow on Sunday in an event a Kremlin critic tried to turn into a protest against a constitutional shake-up by President Vladimir Putin, but many demonstrators chose to voice dissent about other issues instead. Yulia Galyamina, a Moscow city councilor, had urged people to take to the streets to speak out against Putin's proposed political changes by joining an authorized rally already due to be held to mark the murder of a journalist, Anastasia Baburova, and a lawyer, Stanislav Markelov, 11 years ago.

Iran aims to examine downed plane's black boxes, no plan yet to send them abroad

Iran said on Sunday it was trying to analyze the black boxes of a Ukrainian airliner that its military shot down this month, denying a report that a decision had been taken to send the voice and flight data recorders to Ukraine. Canada, which had 57 citizens on the flight in which all 176 people aboard were killed, said on Sunday there were still no firm plans for downloading the recorders. Ottawa and other capitals have called for the black boxes to be sent abroad.
