At least three people were killed and four injured in a possible suicide attack on Monday outside the Danish embassy in the Pakistani capital Islamabad, police and state television said.
"Three dead bodies have been taken away from the scene and there are several wounded," a police constable named Rehman told AFP at the scene of the blast.
"It could be a suicide attack," Pakistan Television quoted an unnamed police investigator as saying, giving the same death toll and saying four others were wounded.
A security source told AFP separately: "It is a bomb attack and the bomb has created a deep crater. We do not have figures for casualties."
