New commercial satellite photos show that a Syrian site believed to have been attacked by Israel last month no longer bears any obvious traces of what some analysts said appeared to have been a partly built nuclear reactor.

Two photos, taken Wednesday from space by rival companies, show the site near the Euphrates River to have been wiped clean since August, when imagery showed a tall square building there measuring about 150 feet on a side.

The Syrians reported an attack by Israel in early September; the Israelis have not confirmed that. Senior Syrian officials continue to deny that a nuclear reactor was under construction, insisting that Israel hit a largely empty military warehouse.

But the images, federal and private analysts say, suggest that the Syrian authorities rushed to dismantle the facility after the strike, calling it a tacit admission of guilt.

"It's a magic act — here today, gone tomorrow," a senior intelligence official said. "It doesn't lower suspicions; it raises them. This was not a long-term decommissioning of a building, which can take a year. It was speedy. It's incredible that they could have gone to that effort to make something go away."
