Officials say a roadside bomb planted on a bridge has struck a rickshaw in northwest Pakistan, killing at least three people

PESHAWAR, Pakistan -- A roadside bomb planted on a bridge struck a rickshaw in northwest Pakistan on Friday, killing at least three people and wounding seven others, officials said.

The attack happened in Mardan district in Khyber Pakhtunkhwa province, police official Sabir Khan said. He said police transported the wounded people to a hospital.

He said a police vehicle crossing the bridge was the target, but the bomb hit a speeding rickshaw, causing civilian casualties. Khan said police were investigating to determine who was behind the attack.

Interior Minister Mohsin Naqvi and other government officials denounced the bombing.

No one claimed responsibility, but such attacks previously have been blamed on Islamic militants including the Pakistani Taliban, known as Tehreek-e-Taliban Pakistan or TTP, a close ally of the Afghan Taliban, which seized power in neighboring Afghanistan in August 2021.

Many TTP leaders and fighters have found sanctuaries and are even living openly in Afghanistan since the Taliban takeover, which also emboldened the TTP.

Pakistan has blamed some attacks on the Islamic State group and some breakaway factions of the TTP, which insists it only targets security forces.
