Foggy Index Strips

Normal sudoku rules apply.

Digits in cages do not repeat, and must sum to the small clue, if given.

Pink strips (of at least 2 cells in length) are hidden in the fog. Digits in a vertical strip in column N indicate the column in which the digit N appears, in the corresponding row. Digits in a horizontal strip in row N indicate the row in which the digit N appears, in the corresponding column. For example, if r2c3 is in a horizontal strip, and contains a 7, then r7c3 contains a 2.

Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.
