We shall show that every strong solution u(t) of the Navier‐Stokes equations on (0, T) can be continued beyond t > T provided u ∈ $L^{{{2} \over {1 - \alpha}}}$ (0, T; $\dot F^{- \alpha}_{\infty ,\infty}$ for 0 < α < 1, where $\dot F^{s}_{p,q}$ denotes the homogeneous Triebel‐Lizorkin space. As a byproduct of our continuation theorem, we shall generalize a well‐known criterion due to Serrin on regularity of weak solutions. Such a bilinear estimate $\dot F^{- \alpha}_{p_1 , q_1} \cap \dot F^{s + \alpha}_{p_2 , q_2} \subset \dot F^{s}_{p, q}$, 1/p = 1/p1 + 1/p2, 1/q = 1/q1 + 1/q2 as the Hölder type inequality plays an important role for our results.
