A bomb blast in northwest Pakistan near the Afghan border killed five police on polio vaccination guard duty and wounded more than 20 on Monday, the latest in a series of attacks by Islamist militants ahead of the Feb. 8 national elections.
The Pakistan Taliban, an umbrella group of militants also known as Tehreek-e-Taliban Pakistan (TTP), claimed responsibility in a statement, Reuters confirmed.
According to a police official, the blast hit a truck full of police on their way to guard a polio vaccination drive in the Bajur tribal district.
