“It was quite a mess,” he told CNN.

He said although he was two floors above the source of the explosions — at least one of which was a suicide bombing, according to Belgian prosecutor Frederic Van Leeuw — many people around him were injured by the blast. He said there about 50 to 60 injured on his level of the airport, while the scenes on the lower levels were worse.

“A lot of people were on the floor. They were injured,” Versele said. “I think I was lucky, I was very lucky. I think I have a guardian angel somewhere.”

President Obama is still in Cuba with his family, but he has been briefed on the attacks in Brussels. The Washington Post: Obama to address the Cuban nation in historic Havana visit.

President Obama will address the Cuban people directly Tuesday, delivering a speech that will be televised live on state television.

The address in Havana’s newly renovated Gran Teatro, before an audience of invited guests of the U.S. and Cuban government, is the keystone event in Obama’s two-and-a-half-day visit to the island. His top advisers said it represented his best chance to outline his vision of the future to ordinary citizens here, and to Cuban Americans at home.

White House deputy national security adviser Ben Rhodes told reporters Monday the speech was “important because it’s the one chance to step back and to speak to the Cuban people, and all of the Cuban people,” including “Cubans in the United States.”

One of Obama’s overarching goals in fostering a diplomatic thaw with America’s longtime adversary, Rhodes said, was “reconciliation of the Cuban American community to Cubans here on the island.”

Still, even the speech’s setting spoke to the ongoing challenge the United States faces when it comes to engaging in a public dialogue in Cuba. American officials had originally hoped to do the address in an open-air setting, which would have allowed more ordinary citizens to attend. Instead, the national theater accommodates roughly 1,000 people, and the two governments evenly divided the tickets.

And even as the president seeks to highlight how his approach to Latin America has paid dividends, a series of blasts at Brussels’s airport and a metro station Tuesday served as a powerful reminder that terrorism overseas continues to threaten global stability. The apparently coordinated strikes have killed at least 26 people.

Back in the USA, Arizona is holding a presidential primary today and there will be caucuses in Idaho and Utah. (In Idaho, the Republicans have already voted.) On the Democratic side, Arizona, with 75 delegates, is the biggest prize.

NBC News: Clinton, Sanders in Primary Showdown for Arizona’s Latino Vote.

PHOENIX, Ariz. — Guadalupe Arreola can’t vote in the Arizona primary Tuesday because she is undocumented, so she has spent the last few weeks encouraging Latinos who can to vote for Democratic candidate Bernie Sanders. On Sunday, she hosted a phone bank at her house. More than 50 people showed up.

“There are people who still don’t know Bernie Sanders, and I want to raise awareness of who he is,” said Arreola, whose daughter Erika Andiola is Sanders’ Latino media spokeswoman.

Martin Hernandez said he likes Clinton’s stance on a number of issues important to Latinos, including healthcare and immigration. An organizing director for the United Food and Commercial Workers Union Local 99, hesaid he especially likes that that she seems to understands the needs of Latino workers.

“I want somebody in the presidency who is going to help workers, especially those in our immigrant community,” he said. “They are the ones who face the most abuse. Many of them are underpaid and their rights are violated by their employers.”

Arreola and Hernandez represent the split that exists among Latino Democrats in Arizona on whether Sanders or Clinton should be the Democratic nominee for president. Both candidates have the backing of prominent Latino leaders, some of whom have appeared in television and radio ads being broadcasted across the state.

I’m not sure if NBC is just trying to make the primary look close or not. According to the Real Clear Politics average, Clinton is leading Sanders in Arizona 53-23, but FiveThirtyEight says there hasn’t been enough polling for them to project a winner. From everything I’ve heard, I think Hillary will win Arizona, and Sanders could win the Iowa and Utah caucuses.

However, there’s a wild card in Utah, according to Al Giordano (from privately distributed newsletter). He says that more and more Mormon women are voting Democratic, and it’s possible they could caucus for Clinton. Mormons absolutely hateand fear Donald Trump, so Giordano argues that it’s even possible that Utah could turn blue in November if Trump is the GOP nominee.

From McKay Coppins (who is a Mormon) at Buzzfeed: Mormon Voters Really Don’t Like Donald Trump — Here’s Why.

So far in 2016, members of the Church of Jesus Christ of Latter-day Saints have proven to be one of the most stubbornly anti-Trump constituencies in the Republican Party — a dynamic that will likely manifest itself in Utah’s presidential caucuses next week.

National polling data focused on Mormon voters is hard to come by, but the election results speak for themselves. Even as Trump has steamrollered his way through the GOP primaries, he has repeatedly been trounced in places with large LDS populations.

In Wyoming, the third-most-heavily Mormon state in the country, Trump was able to muster just 70 votes in the low-turnout Republican caucuses there — losing to Ted Cruz by a whopping 59 points.

In Idaho, the country’s second most Mormon state, Trump lost the primary by 18 points.

And in the Mormon mecca of Utah, the most recent primary poll has Trump in third place — more than 40 points behind Cruz and 18 points behind Kasich.

The pattern holds at the county level as well. As New York Times data journalist Nate Cohn illustrated, the larger the proportion of Mormons in a given county, the worse Trump has generally performed in the primary contest there.

Mitt Romney will caucus for Ted Cruz in Utah.

Philip Bump at The Washington Post: Why Utah hates Donald Trump (Hint: it’s not just about Mormonism).

Donald Trump is getting crushed in Utah.

First, the state’s adopted son, Mitt Romney, went gunning for Trump for weeks on end, and eventually revealed that he was backing Ted Cruz in the upcoming caucuses. Utah is adjacent to Idaho and Wyoming, where Trump has seen two of his biggest losses so far, both to Cruz. In a poll from Y2 Analytics released over the weekend, Trump comes in third, 42 points behind Cruz. (If Cruz wins more than half of the votes in the state, he gets all of the state’s 40 delegates.)

What’s even more remarkable, though, is that another poll suggested that Trump would lose to either Democrat in Utah in the general election. Utah is, of course, one of the reddest states — if not the reddest state — in the country. “Any matchup in which Democrats are competitive in the state of Utah is shocking,” Brigham Young University’s Christopher Karpowitz said to the Deseret News about that result.

Why? Mormon voters, of course; but polling (see lots of graphics at the link) show that people of any religion who are regular church-goers are more likely to be anti-Trump.

What may be prompting the stiff resistance to Trump, then, isn’t just that Utah is home to a lot of Mormons — it’s that those Mormons are more religious and that religious voters are more likely to view Trump with hostility.

The good news for Trump is that most of the states with the largest groups of regular churchgoers have already voted. Most are in the Bible Belt, as you might expect — a region where Trump did very well. Political beliefs are more complicated than they might appear at first glance. Sort of like religious ones.

It’s an interesting wild card, and something to keep an eye on. I’d certainly expect Jewish voters to be frightened by Trump’s strong-man campaign.

So . . . lots of things happening around the world today. What stories are you following? Dakinikat will post a live blog this evening for us to discuss primary and caucus results.
