Abdulla Abjada's understanding is coming along slowly, letter by letter, word by word. He spends most of his days in a dusty church courtyard perched over his Portuguese phrase book.

"How did I get here? Ya!" he laughs. "It was a little bit … complicated."

When Syria's civil war tore apart his city of Aleppo three years ago, he says, his brother was arrested and tortured.

"Fifteen days, horrifying, torturing, abusing, and he did not see the sunlight," Abjada says.

He says he faced a terrible choice: the government demanded he join the army to fight the rebels, while the rebels insisted he fight the government.

"And in both sides, we are killing each other, we are Syrians," he says. "So I choose not to kill anybody and I leave the country."

But where to go? Most of his friends ended up in European or Middle Eastern refugee camps — safe, but essentially imprisoned.

Alex Cuelho, a priest who runs the shelter for refugees at Sao Joao Batista church, says the tide of public opinion seems to be turning against them. (Kim Brunhuber/CBC) "Canada and Brazil, they are the only two countries they are giving Syrians a safe way to make a new life," Abjada says.

Abjada is one of more than 2,200 Syrians who have settled in this country of 200 million. Brazil has accepted the third-most Syrians in the Americas behind Canada and the U.S.

He arrived this year via Turkey, and has been staying at Sao Joao Batista, a small church in the Botafogo neighbourhood of Rio de Janeiro. The church has become a way station for close to 30 refugees.

As Abjada recounts his story, another Syrian refugee arrives from abroad. He says his name is Ali, and Abjada offers to help him settle in.

However, a shift in the country's politics means Ali could be one of the last Syrians to arrive in Brazil.

Under former president Dilma Rousseff, the country had an "open-arms" policy. One former minister said his government's goal was to accommodate 100,000 Syrians in five years. But now Rousseff faces impeachment proceedings because of corruption scandals.

Michel Temer, the interim president, has advertised a law-and-order administration with security as a top priority, and he is abandoning efforts to bring in more refugees.

Alex Cuelho, the priest who runs the shelter at Sao Joao Batista, says with increased visitors for the Olympics and recent attacks in Europe, the suspicion is growing that Brazil could be importing Syrian terrorists.

"It brought a negative view towards the Syrians," Cuelho says. "Now there's prejudice and fear of receiving Syrian refugees."

Ahmad Hamada, who set up a stall selling Middle Eastern foods, says it required the intervention of the Rio's mayor to save his business (Kim Brunhuber/CBC) Those negative attitudes and emotions have already touched Ahmad Hamada.

Soon after he set up a rolling cart on a busy street in downtown Rio selling Middle Eastern foods like falafel and kibe, he received visits from the police, who seemed to be targeting his stand.

"The police come, every day they say, 'You cannot sell here, you cannot sell here,'" Hamada says, next to his stand in front of a movie theatre.

It took the intervention of a high-profile customer, Mayor Eduardo Paes, to allow him to stay.

"He is like my mother because he sees me, what happens, [he says,] 'No, no problem, you can stay,'" Hamada says.

His plea to suspicious Brazilians: just get to know us.

That process has already begun in a downtown classroom.

"Today we're going to speak about the shaddah," says Adel Bakkour, writing the Arabic sign in blue marker on a small white board. Ten Brazilian students, most in their late 20s, take notes.

He decided to flee, and Brazil offered him refuge. Within a month of arriving, Bakkour says, he got a Brazilian work permit and free Portuguese lessons.

He wanted to give back‚ so he offered to teach Arabic night classes run out of a Hebrew school. Part of his lesson plan is Syrian culture.

"Some of them ask me if I can marry four women because of the religion," he says, smiling. "Do you really cut the hand of the thief? No, in Syria we don't. Any small idea I give will be passed on to other people."

He says there was so much interest he's going to start a second class. And his students say their most useful lesson had little to do with the alphabet.

"Last class he was telling us stories about back home. It was interesting hearing what he thinks about Brazil and Rio, how he's been dealing with everything here," says student Amanda Nicotina.

Bakkour explained "why those people had to flee from home, from their country," adds Catherine Brillant. "This part of the world, I didn't really know much about it."
