Last Friday, Israel launched massive air strikes on Iran, prompting Tehran to retaliate with barrages of missiles.
In a video message that day, Prime Minister Benjamin Netanyahu told the Iranian people that in addition to Israel's aim of thwarting Iran's nuclear programme, "we are also clearing the path for you to achieve your freedom".
Some sections of Iran's splintered opposition have rallied behind Netanyahu's call. Others are mistrustful of his objective.
There are no official opposition groups inside Iran, where authorities have long cracked down on dissent, including a wave of mass executions and imprisonments in the 1980s.
Since then, most opposition groups have operated from abroad, including two of the most organised groups: the pro-monarchy supporters of Reza Pahlavi, son of the last Shah of Iran, and the exiled Mojahedin-e Khalq Organisation (MEK/MKO).
