AP story says:

>A helicopter carrying Iranian President Ebrahim Raisi suffered a “hard landing” on Sunday, Iranian state media reported, without elaborating. Some began urging the public to pray for Raisi and the others on board as rescue crews sped through a misty, rural forest where his helicopter was believed to be.

Way too early to say, better to wait and see

No details at all, presumably not much will be known until it is found. Presumably if Iran had even a tiny reason to blame it on an enemy, they would already be doing that.
