TORONTO - William Shatner is expressing his sadness over the loss of "Star Trek" co-star Leonard Nimoy.

In a brief statement given to The Canadian Press by his publicist, Shatner says he "loved him like a brother."

The Montreal native added that "we will all miss his humor, his talent, and his capacity to love."

Nimoy's son, Adam Nimoy, said the actor died Friday of end-stage chronic obstructive pulmonary disease at his Los Angeles home.

He was 83.

Nimoy played Mr. Spock alongside Shatner as Captain James T. Kirk on the original "Star Trek" series from 1966 to '69.
