Iran has condemned Bahrain over the jailing for life of a Shiite opposition leader, accusing Manama of wanting to "intensify its suppression" of dissent.
Bahraini Sheikh Ali Salman and two of his aides were sentenced on Sunday for "acts of hostility" against Bahrain and spying for rival Gulf state Qatar.
The ruling against Salman, who headed the now-banned Al-Wefaq movement, has been called a travesty by rights groups.
Iran's foreign ministry spokesman Bahram Ghasemi said the verdict "leaves no doubt for the international community that the government of Bahrain... intends to intensify its suppression."
