Iran's supreme leader, Ayatollah Ali Khamenei, has praised the country's recent attack against Israel while not referring to likely retaliation by Israel.

Iran launched a massive attack against Israel from April 13. On Friday, explosions occurred in central Iran. Multiple US media reported that they were a retaliation by Israel.

Iran's state-run TV has reported that Khamenei spoke to commanders of the country's armed forces on Sunday. In the speech, he referred to the Iranian attack. He said the other side cares about how many missiles were fired or hit their targets, but it is significant that the Iranian people and military demonstrated their willpower to the world.

He did not touch on apparent countermeasures by Israel.

Observers say Iran's supreme leader indicated the country currently has no intention of raising tensions by carrying out further attacks.

On Saturday, another blast with unknown causes reportedly occurred at a base of an Iran-backed militia group in Iraq.
