AFP has a concise takeaway from today’s Friday prayer, delivered by Khamenei:

Iran’s supreme leader Ayatollah Ali Khamenei warned opposition groups they will be “confronted” if they jeopardise the nation’s security, in an address during Friday prayers in Tehran.
“Those who draw swords against the regime will be confronted,” Khamenei, who has the final say on all national issues, said as he led the weekly Muslim prayers at Tehran university.
“Differences of views should not lead to conflicts … the policy of the regime is to work with the majority. But if opposition groups have ideas that are against the nation’s security and the principles of the regime, they will be confronted,” he said.

For greater detail, Josh Shahryar has done a commendable job of posting a live translation of Khamenei’s speech, where you can find such nuggets as Khamenei recalling the victory of Iran’s soccer team over the United States in the 1998 World Cup.
