TERROR IN BRUSSELS: The arrests keep coming, as a suspect is arrested by authorities in Belgium – but it may or may not be the individual Belgian media have identified as the third perpetrator of the attacks. Najim Laachraoui, a suspected bomb maker for the Islamic State, was allegedly caught on camera with brothers Khalid and Brahim El Bakaroui pushing suitcases laden with explosives through the airport.

The confusion is just part of the overall picture of what is happening in Brussels, which has emerged in the last few months as the terrorist capital of Europe, and the source of many foreign fighters traveling to Syria to join the Islamic State.

In the United States, yet another attack in Europe is causing many to examine how vulnerable the U.S. is to a similar attack, and what kinds of changes may be needed to counteract the persistent threat. President Obama is facing pressure to change course on his anti-ISIS strategy, which so far, has had a fairly low profile, even as much of the world is gripped by fear the terrorist group has managed to instill.

UKRAINIAN HERO SENTENCED: The trial of the Russia-Ukraine conflict ended Tuesday, with a Russian judge handing down a sentence of 22 years to Nadiya Savchenko, who was accused of striking and killing two Russian journalists in eastern Ukraine in 2014.

Savchenko staged hunger strikes, and was even elected to the Ukrainian parliament while in custody. U.S. officials have urged Russia to release her.

TRUMP’S TEAM The Washington Post dove a little deeper into the team of foreign policy experts Donald Trump detailed in an editorial board meeting, and the Republican front-runner’s squad has some interesting features. It includes former administration officials and members of the military. It also includes a 2009 college graduate who lists Model UN on his LinkedIn resume, and Joseph Schmitz, the son of a member of the John Birch Society. Schmitz is also the brother of Mary Kay Letourneau, “the ex-schoolteacher who received seven years in prison for child rape after starting a relationship with a 13-year-old student,” the Post reports.
