PESHAWAR: At least three people were killed Wednesday when a bomb exploded in the Alemgar area of Safi tehsil in Mohmand Agency.

Official sources said that suspected militants had planted the Improvised Explosive Device (IED) in front of the house of a local named Taj Gul, killing one of his sons Sakhi Gul and his nephew Maskeen on the spot while his other son Muhammad Agul, who is a Union Council polio worker, was left injured.

The injured polio worker was shifted to the Camp Hospital in Muhammad Gat, where he later succumbed to his wounds.

No one has claimed responsibility for the attack.

Polio team members have been frequently attacked by militants in the Federally administered Tribal Areas (Fata).

Militants allege that polio vaccination is a cover for espionage or a Western-conspiracy to sterilise Muslims.

Mohmand is one of Pakistan’s seven tribal agencies near the Afghan border which are rife with militancy and are said to be strongholds of Taliban and Al Qaeda operatives.
