It seems that the DHARMA Initiative has infiltrated ABC News.

ABC News' Bay Area affiliate, KGO-TV, is covering the San Bruno, Calif., explosion with a breaking-news photo collage that features, among other images, a television still from an episode of the popular drama "Lost."
The image appears to have been uploaded to KGO-TV by a Web visitor as part of the station's uReport initiative.

This screen grab from the "Lost" fan site was taken at 5:10 p.m. EST.
The user's prank seems to have been "lost" on the news website, which includes no mention of the image as a television still.
The photograph of a burning van featured in the top right corner of the KGO-TV photo-spread seems to be identical to an image of a smoldering van from the Emmy-winning series that has been posted on "Lost" fan websites like TV Fanatic.

The burning van appears in an episode when a young Ben needs Sayid's help to escape DHARMA and get to the Others. Sayid's plan is to trick Ben into thinking he's helping him escape, and then kill him. Young Ben sends this flaming van careening into a house to create a diversion, and then frees Sayid.
