ANKARA The Turkish Foreign Ministry said Sunday it is closely following the case of a Turkish PhD student who was detained in the US last month after writing a pro-Palestinian article for a student newspaper. Rumeysa Ozturk, 30, was one of four students who wrote an op-ed in The Tufts Daily at Tufts University, criticizing the school’s response to student activists demanding the school "acknowledge the Palestinian genocide," disclose investments and divest from companies with ties to Israel.
