Islamabad: At least four soldiers were killed and three others injured in a suicide attack on a security check-post in Pakistan's restive North Waziristan tribal region on Wednesday.

A suicide bomber struck his explosive-laden vehicle into a security check-post in Watta Khel, killing four and injuring three other officials.

Following the attack, fire erupted at the check-post resulting in casualties. In retaliation, the security forces began aerial firing. Residents said they also heard firing after the attack.

No group claimed responsibility for the attack. Major Taliban group in the region led by Hafiz Gul Bahadar has signed a peace deal with the government in North Waziristan. Both do not attack each other under the agreement.

Some other militant groups, including the banned Tehrik-e-Taliban Pakistan (TTP), operate in the region. The authorities blame the TTP and its affiliated groups for this attack.

The suicide bombing occurred a day after the US drone killed 17 suspected militants in North Waziristan.
