Sanaa, Yemen (CNN) -- A suicide bomber dressed in a military uniform killed at least 101 soldiers Monday at the central security headquarters in Yemen, Interior Ministry officials said.

More than 70 were injured, with some in critical condition, authorities said.

The blast targeted a military parade rehearsal in Sabeen Square in the capital Sanaa, said Mohammed Albasha, a spokesman the Yemeni Embassy in Washington.

He said that it was too early to know who was responsible but that suicide attacks are "the hallmark of al Qaeda."
