BOSTON — A Turkish student detained by federal officers as she walked along a street in a Boston suburb is the latest supporter of Palestinian causes to be swept up in the Trump administration’s crackdown on immigrants who have expressed their political views.

Rumeysa Ozturk, 30, a doctoral student at Tufts University, was swiftly moved out of Massachusetts, a demonstration of how U.S. Immigration and Customs Enforcement is sending immigrants who are taken into custody to detention centers or deporting them before a federal judge has a chance to weigh in on their case and possibly halt the actions.

Ozturk, who was detained Tuesday shortly after she left her home in Somerville, had been moved to an ICE detention center in Basile, Louisiana, by the time her lawyer went to court and a judge ordered her to be kept in the state, U.S. government lawyers said in a court document Thursday. They said they made her lawyers aware that she was being moved there and facilitated contact with her Wednesday night.

A senior Department of Homeland Security spokesperson said federal authorities detained Ozturk after an investigation found that she had “engaged in activities in support of Hamas, a foreign terrorist organization that relishes the killing of Americans.” The department didn’t provide evidence of that support. Secretary of State Marco Rubio said Trump officials had revoked visas for at least 300 people, including Ozturk: “We do it every day.”

“We gave you a visa to come and study and get a degree, not to become a social activist, to tear up our university campuses,” Rubio told reporters in Guyana.

Friends and colleagues of Ozturk said she was not closely involved in pro- Palestinian protests last spring. Her only known activism, they said, was co-writing an op-ed in a student newspaper that called on Tufts to engage with student demands to cut ties with Israel.

“To my knowledge, the only thing I know of that Rumeysa organized was a Thanksgiving potluck,” said Jennifer Hoyden, a close friend who studied with Ozturk at Columbia University’s Teachers College. “There’s a very important distinction between writing a letter supporting the student Senate and taking the kind of action they’re accusing her of, which I’ve seen no evidence of.”

Hamas invaded Israel on Oct. 7, 2023, in an attack that killed 1,200 people, mostly civilians. Israel’s retaliatory offensive has killed over 50,000 people, according to Gaza’s Health Ministry, and destroyed much of the enclave.

Ozturk’s arrest appears to be part of President Donald Trump’s pledge to deport students who engage in “pro-terrorist, anti-Semitic, anti-American activity,” a label the administration has applied broadly to those who criticize Israel. This month, U.S. agents detained Mahmoud Khalil, a legal U.S. resident and Palestinian activist who played a prominent part in protests at Columbia last year. He is facing possible deportation.

Dr. Rasha Alawieh, a kidney specialist from Lebanon who was due to start as an assistant professor at Brown University, was deported this month — after a federal judge ordered that she not be removed until a hearing could be held. Homeland Security officials said Alawieh was deported, despite having a U.S. visa, because she “openly admitted” to supporting a Hezbollah leader.

A University of Alabama student also has been detained by ICE, the university confirmed. The Crimson White, the student newspaper, reported that Alireza Doroudi, a doctoral student from Iran studying mechanical engineering, had been detained.

But neither university nor the newspaper explained why Doroudi had been taken into ICE custody.
