One person was killed and 45 others were injured when serial bomb blasts rocked Pakistan's port city of Karachi on Monday .
The six "low-intensity" explosions occurred in Banaras Chowk, Orangi town, Shahrah-e-Noor, Paharganj, Qasba mor and Mangho pir areas, police said.
At least nine people were injured in Banaras Chowk while five people were wounded in a blast in a minibus in Shahrah-e-Noor area.
"There were a series of blasts in Karachi which were of low intensity and have
not caused any damage to property," Karachi police chief Waseem Ahmed said.
The blasts were apparently carried out to create an atmosphere of fear and tension, he said.
The explosions came a day after a bomb blast near Islamabad's Lal Masjid killed 20 people, hours after Islamic hardliners took out a rally demanding President Pervez Musharraf's public hanging.
Ahmed said the police were on high alert and have taken all measures the secure the life and property of people.
