(Adds background on Monday’s rally)
TEHRAN, June 16 (Reuters) - Iran’s defeated presidential candidate Mirhossein Mousavi urged his supporters not to attend a planned rally in Tehran on Tuesday, his spokesman said.
"Mousavi ... urged his supporters not to attend today’s rally to protect their lives. The moderates’ rally has been cancelled," the spokesman said.
State television said seven people were killed at the end of a pro-Mousavi rally on Monday which drew many tens of thousands of his supporters.
They had planned another rally later on Tuesday, but supporters of President Mahmoud Ahmadinejad called for a counter-rally at the same Tehran square, possibly setting the scene for more confrontation.
