Three explosions occurred early today in Mexico City, destroying a building entrance at a leading political party’s headquarters, and reportedly damaging the Federal Electoral Tribunal and a Scotiabank branch.

Authorities also deactivated a homemade explosive device at a second Scotiabank branch near the tribunal, Mexican news media reported.

Authorities told Mexican news media there were no injuries, and the explosions did not provoke any fires.

Bank of Nova Scotia has closed one branch in Mexico City after the bomb blast did structural damage to the building. No one was injured in the explosion.

Security has been stepped up at the Toronto-based bank’s other Mexico City locations.

Scotiabank operates in 50 countries worldwide. Its Mexican division, Scotiabank Inverlat, is the country’s seventh largest commercial bank with more than 400 branches.
