Gunmen suspected to be Al-Shabaab militants ambushed and fatally shot four Kenyan construction workers on Saturday noon.
According to the police, the four were part of a group working at a construction site at a hospital near the Dadaab refugee camp.
The site is located at the border of Kenya and Somalia, a common operation zone for the Al-Shabaab terror group.
The group of eight workers were resting when armed men suddenly began shooting at them from close range, killing four of them.
During the incident, the rest of the workers managed to escape unharmed.
According to reports, the terror group could have staged the attack after the contractor failed to heed their initial call to halt the construction.
Al-Shabaab's recent attacks have forced the government to suspend plans to reopen the 700-kilometer Kenya-Somalia border.
The Interior Ministry has since moved quickly to beef up security in the area in the aftermath of the tragedy.
The occurrence comes barely two days after police officers in Mandera recovered explosive devices that were about to detonate.
In a similar incident on March 29 this year, six Kenyan businessmen were shot dead by the militia in Dhobley, a border town between Kenya and Somalia.
While confirming the incident, the police linked the attack on the six Meru businessmen to Al-Shabaab terrorists.
Liboi Deputy County Commissioner Ali Manduku noted that the terrorists sought to affirm their dominance within the border town through such violent means.
