All of Britain commemorated the week anniversary of the attack at noon. Woods had a short chip to the par-5 14th green when a siren sounded and St. Andrews went still. Asked after his round what he was thinking about during those two minutes, he mentioned his mother, Kultida.
``I was more thankful than anything else because my mom was in the building right across the street from where the bomb blew up,'' Woods said. ``I was very thankful that my mom is still here.''
Mrs. Woods had been touring Europe with friends. Woods said he didn't even know until Wednesday that his mother was in London the day of the bombings, exactly one week ago. He found out from his swing coach, Hank Haney.
``She doesn't tell me anything. That's kind of how our family is,'' Woods said. ``If you're injured or you're hurt or you're sick or anything, you don't tell anyone. You just deal with life and move on.''
Mrs. Woods was in the gallery watching her son post a 6-under 66 for the early lead.
``I heard, 'Nice putts' a couple of times,'' Woods said.
Meanwhile, Jack Nicklaus stood facing the bleachers on the 16th hole, his arms behind his back, when the airhorn sounded. In the bleachers, thousands of fans stood, their silence broken only by the occasional calls of nearby gulls.
``It was very appropriate, I would say,'' Nicklaus said.
The flag at the historic clubhouse at the Old Course was lowered to half staff.
At least 52 people were killed and hundreds injured when bombs went off a week ago in three subway trains and a double-decker bus.
Officials of the Royal & Ancient Club, which runs the British Open, said they have beefed up security in the wake of the attacks.
