Two bombs exploded near buses carrying navy officials in Pakistan's southern city of Karachi on Tuesday, killing one man and wounding over 30, officials said.
Pakistan Navy spokesman commander Salman Ali confirmed one incident and said he was gathering details for the second blast that took place in another part of the sprawling city.
"Explosive devices were planted on the road and they exploded as the buses were passing. Both buses were carrying navy officers," senior police officer Iqbal Mehmood said.
Karachi, the country's commercial hub, is also home to the Pakistan navy.
Militants linked to al Qaeda and Taliban have repeatedly carried out attacks in the city in the past.
In 2002, 11 French engineers and technicians working on the construction of submarines for the Pakistani navy were killed, along with three Pakistanis in a suicide car bombing outside a hotel in Karachi.
The city also has a long history of bloody feuds between rival ethnic, political and sectarian groups, in which hundreds of people have been killed.
Last week, 22 people were killed in a bomb blast at a club for card players.
