Pietersen voices fears after Mumbai attacks

(CNN) -- England cricket captain Kevin Pietersen said the Mumbai terror attacks "sent a shiver down his spine" as his players were told that no-one will be forced to return to India for a scheduled two-Test series.

Pietersen made his remarks to Sunday's News of the World on returning to England from his team's aborted tour of India -- cutting short their one-day series after the attacks which have left at least 195 people dead.

England are due to return for the Tests scheduled to be played before Christmas, but English and Wales Cricket Board chief executive Hugh Morris said it was up to the individual players if they wanted to go back.

"I do not think we would force anybody to do anything," said Morris at a press conference at Heathrow Airport on Saturday night.

But he added: "We are committed to going back, to playing in the Test series assuming it is safe to do so."

Morris, who offered his condolences to all those affected in the attacks, said any decision would depend on the security advice.

England stayed earlier in their tour at the Taj Mahal Palace hotel and were due to visit again for the second Test, which has now been switched from Mumbai to Chennai in a bid to calm fears.

The first Test is scheduled to start on December 11 in Ahmedabad with a warmup game next week.

However Morris admitted the players were concerned about the current situation. "There's a degree of nervousness, there's no doubt about that," he said.

"That's only natural. It's affected everybody."

Cricket has been badly-hit by the attacks, with the lucrative Champions League Twenty20 tournament postponed with organizers yet to set a date for its staging.
