Three bombs exploded simultaneously in Mexico City in the early hours of Monday, damaging property but injuring no one.
The bombs exploded at the headquarters of the Institutional Revolution Party (PRI), outside the country's Electoral Tribunal and in a Scotiabank branch. Police located and disarmed another bomb in a different Scotiabank branch.
Mexico City Mayor Alejandro Encinas said the explosions were "creating a climate of uncertainty."
The explosions came a day after more than 20,000 people marched in the southern city of Oaxaca to demand the withdrawal of federal police who were sent in on Oct. 29 to end violence linked to a five-month protest against the state's governor, Ulises Ruiz. Demonstrators claim Ruiz, a PRI member, rigged the 2004 elections.
Protest leader Flavio Sosa said his movement was not responsible for Monday's blasts.
