The National Police Service said that its security officers managed to recover two AK 47 assault rifles, Improvised Explosive Device (IED) making materials and other crude weapons.
Four civilians including a teacher and a small child were, however, killed as the criminal gang targeted the nearby telecommunication mast.
A security team on border patrol responded swiftly and managed to repulse the attackers, eventually killing two members, as their accomplices fled.
“Security agencies have been mobilized and are pursuing the rest of the attackers,” the National Police said in a statement.
The onslaught comes barely a day after al-Shabaab attacked a military base used by Kenyan and US forces in the coastal region of Lamu on Sunday. Three people were killed, including a US service member and two civilian defense contractors.
Kenya has experienced numerous terror attacks since the country sent troops to Somalia in 2011 to rout out the militants.
al-Shabaab militants have, in the past, staged attacks on Kenyan soil, targeting security officers and civilians in border regions.
