New Delhi ? A bomb detonated in a crowded bakery popular with foreigners in western India, killing nine people and wounding 57, officials said today, the first terrorist attack in the country since the 2008 Mumbai massacre.

The blast Saturday in the city of Pune, 125 miles southeast of Mumbai, threatened to damage new efforts to reduce tensions between nuclear-armed rivals India and Pakistan, with Hindu nationalist leaders placing blame for the attack on InHome Secretary G.K. Pillai said the blast occurred at 7:30 p.m. at the German Bakery, near the Osho Ashram, a renowned meditation center.

Pillai said the ashram, about 200 yards from the bakery, had been surveyed by David Headley, an American facing charges in Chicago for allegedly scouting targets for the Mumbai attack.
