QUETTA At least 29 oil tankers, carrying fuel for the US-led coalition forces in Afghanistan, were set ablaze in a pre-dawn attack in Kachhi district of Balochistan on Saturday, during which three people were also injured. The official sources said the tankers, heading towards Kandahar, were parked near Sarawan Hotel in Mitri area, 25km away from Sibi, when more than 20 armed attackers targeted them with sophisticated weapons. As a result, three oil tankers caught fire which gradually engulfed the remaining vehicles too. Three people, including two Levies officials identified as Hakim Ali and Khamisa, sustained bullet injuries and were shifted to a hospital in Sibi where the condition of one of them is stated to be serious. Three Levies men were guarding the tankers at the time of the attack. An eyewitness said the attackers, who came on foot, first sprayed a volley of bullets and then fired a rocket before managing to flee under the cover darkness. Home Secretary Akbar Hussain Durrani told reporters that neither the contractor nor the drivers of the oil tankers inform the local administration of their presence at a roadside hotel and parked their vehicles while ignoring safety procedure. He said the tankers were parked so closely that when some them caught fire, the majority of the drivers could not access their tankers and the fire destroyed all the vehicles within a short span of time. The local administration sought help from their counterparts in the nearest town of Sibi. But the only available fire engine, which was sent immediately, failed to extinguish the inferno, which gutted the vehicles completely. The huge flames also reduced the four nearby shops to ashes. The heavy contingents of Levies and other law enforcement agencies cordoned off the area and started a search operation in the area. According to Deputy Commissioner Kachhi Abdul Mateen, who briefed newsmen, the Levies personnel, present at the site, offered resistance and resorted to retaliatory fire. But one of them received bullet wounds while another had been hospitalised owing to the burn wounds. He expressed the hope to capture the culprits, saying different teams of Levies Force were making efforts to trace out the culprits while following their footprints. It may be mentioned that it was second large scale attack on the Nato oil tankers within a week in Balochistan as the militants had set ablaze 40 tankers at a private terminal in Aktherabad area in the outskirts of Quetta. However, no arrest has so far been made in connection with these latest attacks.
