McALLEN, Texas (AP) — A nun who was taken into immigration custody last month in Texas said Thursday that she went into a cold sweat as two armed men approached her while she walked to Sunday Mass in her habit, thinking about the day’s Bible readings and carrying little more than her rosary and cellphone.

“Honestly, in that moment, I did not understand what was going on, what was happening to me,” Sister Leticia Ugboaja said at a news conference at Our Lady of Sorrows Church in McAllen, where she spoke out for the first time since U.S. Immigration and Customs Enforcement officers arrested her on June 28.
