Can women go to tarawih prayer in Ramadan without their mahram?

There is no private condition for a woman to go from one place to another in the city. There may be a security issue. When viewed from the religious aspect, woman or women can travel alone in the city, the mahram requirement must have been mispronounced or misunderstood. If it is a security threat, it is not a problem that can be solved with mahram anyway.
