With the white throat and the underdeveloped gape, this looked like an immature Sand Martin to me. But upon consultation with Tonji R. and Rob H., it turned out to be just a garden variety Barn Swallow. The fork in the tail is too deep for a Sand Martin. 
Barn Swallow (Hirundo rustica, migrant, immature)
