(RFE/RL) -- At least five people have been killed in an arson attack on a building in the southeastern Iranian city of Zahedan, where a bomb attack on a Shi'ite mosque last week left 25 people dead.
Iran's official English-language Press TV said dozens were also injured in the blaze at the local subsidiary of Iran's Mehr Financial and Credit Institute.
Witnesses told RFE/RL's Radio Farda that the arson attack occurred on May 31. Zahedan is the capital of Sistan-Baluchistan Province, home to mostly Sunni ethnic Baluchis.
A senior police official was earlier quoted by the Mehr news agency as saying security had been restored and a number of people -- both Sunnis and Shi'a -- have been arrested in Zahedan following the sectarian violence.
But Radio Farda reports that at least two people -- apparently Sunnis -- were killed in renewed violence in the city on June 1.
