People with ties to American universities, most of whom have shown support for pro-Palestinian causes, have been detained in the Trump administration's crackdown on immigrants. Federal officers detained 30-year-old Turkish student Rumeysa Ozturk on Tuesday as she walked along a street in suburban Boston. A senior Department of Homeland Security spokesperson said without providing evidence that an investigation found Ozturk, a doctoral student at Tufts University, 'engaged in activities in support of Hamas,' which is also a US-designated terrorist group. This month, immigration enforcement agents arrested and detained Mahmoud Khalil, a legal US resident, Palestinian activist and graduate student who was prominent in protests at Columbia last year.

Leqaa Kordia, a resident of Newark, New Jersey, was detained and accused of failing to leave the US after her student visa expired. Ranjani Srinivasan, an Indian citizen and doctoral student at Columbia, fled the US after immigration agents searched for her at her university residence. University of Alabama doctoral student Alireza Doroudi of Iran was detained by ICE on Tuesday.
