Thousands of Iranians in southwestern Iran turned their anger toward Britain Monday at funerals for six people killed in twin bombings that Iran has blamed on London.

State television showed mourners in the city of Ahvaz chanting anti-Western slogans as they carried coffins of the dead through the streets of the city.

An editorial today in Iran's Kayhan International newspaper alleged Britain was behind Saturday's blasts and several other recent bombings in the city. Sunday, Iranian President Mahmoud Ahmadinejad said he was "very suspicious" about Britain's role. Britain has denied any involvement.

Relations between Tehran and London have deteriorated sharply in the past month, over British support for a U.S. push to refer Iran's nuclear case to the United Nations Security Council for possible sanctions.

For its part, Britain has accused Iran of backing insurgent attacks on British forces in nearby Iraq.
