  We derive exact solutions of the seven-dimensional Einstein-Maxwell equations
for a spacetime exhibiting Poincare invariance along four-dimensions and
spherical symmetry in the extra-dimensions. Such topology generically arises in
the context of braneworld models. Our solutions generalise previous results on
Ricci-flat spacetimes admitting the two-sphere and are shown to include
wormhole configurations. A regular coordinate system suitable to describe the
whole spacetime is singled-out and we discuss the physical relevance of the
derived solutions.
