TORONTO (Reuters) - The Toronto Stock Exchange's main index ended nearly 100 points higher, boosted by energy issues, which rose on fresh Middle East tensions spurred by Iran's seizure of 15 British navy personnel, as well as by strength in financials and materials.

The S&P/TSX composite index closed up 98.02 points, or 0.8 percent, at 13,237.66, ending the week with a 3.2 percent rise.

Oil and gas shares rose 1.2 percent as U.S. crude oil continued to climb after Thursday's rally, moving above $62 a barrel after the seizure of the British navy personnel.

Canadian Natural Resources Ltd. rose C$1.24, or 2 percent, to C$62.43, while EnCana Corp. climbed 64 Canadian cents, or 1.1 percent, to C$58.

Overall, eight of the TSX index's 10 main groups were higher. The information technology and health care sectors were down 0.1 percent and 0.4 percent respectively.
