MANDERA, Kenya, Sept. 26 (Xinhua) -- Kenya's security forces on Thursday heightened security along its border with Somalia after twin blast killed three people among them two police officers in the latest incident of insecurity in the East African nation.
The two police officers and a civilian were killed and six others injured in two simultaneous terrorist attacks in northern Kenya bordering the war-torn Somalia.
The twin attacks in Wajir and Mandera border towns, which occurred on difference of eight hours from each other, also left 12 vehicles and entire government offices completely reduced into shreds of metals bars and dust of crumpled rubble, an indication of the heaviness of the impacts of the attacks.
In the first incident, the Mandera County police commander Rono Bunei said they have beefed up security along the border to thwart any cross border incursions of terrorists from neighboring Somalia.
"We have increased police presence in the region to ensure peace at all time," Bunei said on Thursday.
He said two officers, who were manning the camp at the time, come under hails of indiscriminately fired bullets punctuated with hurling of hand grenades.
"We lost two of our officers and another one was seriously injured. We are now airlifting the critically wounded officer to Nairobi for better treatments," he said.
Albert Hama, the Mandera County Administration police commander said a total of 12 vehicles were burnt down beyond recognition by the explosives hurled at the camp by the assailants who were believed to members of the Al-Qaida proxy in the neighboring Somalia.
"The attackers whom we suspected arrived on foot took positions around the ill-fated administration police camp and started opening fire from all direction at 3 a.m. to confuse our officers on duty. They then hurled several explosives including propelled hand grenades," Hama said, while taking the reporters around the camp.
"Among the cars were those of the District Officer and three others belonging to other government ministries. The eight vehicles were brought for safety by members of the civilians who fear their cars carjacked by militia," he added.
The Al-Shabaab group said its the twitter handle "HSM_PR" that "Mujahideen forces last night raided a Kenyan police base in Mandhera town, in the Muslim NE region, killing two and injuring 3 others."
And in the second incident that occurred in Wajir town targeted a civilian walking on the street at around 7:30 p.m., killing one and leaving five others with critical injuries, according to the Wajir County police commander David Kirui.
Kirui said "the assailants whose number we couldn't establish at the moment hurled two hands grenades at a group of people walking towards their respective homes along Soko Mjinga (The market of the idiots)."
"A middle age man in the group was killed instantly, while five of his colleagues were injured," he said.
"The victims were lucky that one of the Russian made hand grenade thrown at them failed to detonate. If the two hand grenades exploded as intended by the attackers, the number of death and injuries could have been bigger," he said.
The county police commander said the injured people were been treated at Wajir district hospital adding that, three among the five who were critically wounded, were been referred to Garissa general hospital and they were awaiting to been airlifted shortly.
He said a middle age man who is also among those who sustained slight injuries was held as a suspect by the police at the hospital and will be interrogated on his role in the attack after he get conscious.
The county police chief said they have called on special anti- ballistic military officers from Wajir military camp to assist them in detonating the unexploded hand grenade, which is guarded at the scene of the attack by the anti-terrorist police unit since last night.
The attacks come after the country was shocked by one of the worst terror attacks in the recent past at Westgate shopping mall in Nairobi on Saturday.
Al-Qaida allied Somali militants have claimed responsibility for the attack which also saw 62 civilians, six security officers and five terrorists killed and 11 suspects arrested for questioning.
Foreign forensic experts who are investigating the Westgate incident are expected to establish the identities of the terrorists who stormed the shopping mall in Nairobi and opened fire on the shoppers.
The investigations involve finger-printing, DNA and ballistics examination, will go on for the next seven days and will establish the identities of the slain militants.
