Japanese residents in Manchester, England, expressed shock that the deadly terrorist attack at a concert hall took place in a city known for welcoming different cultures.

Aya Homei, a lecturer of Japanese studies at the University of Manchester, told The Japan Times on Wednesday that she was working at home in the city¡¯s suburbs, some 7 km from its center, when she learned of Monday night¡¯s attack through her German husband via Twitter.

Neither Homei nor her acquaintances were harmed in the attack, but Monday¡¯s explosion ¡ª the latest in a spate of deadly strikes across Europe ¡ª confirmed her fears that terrorism ¡°is no longer someone else¡¯s matter,¡± she said.
