(Adds Karua quotes)

GARISSA, Kenya, Feb 17 A man was killed when the
bomb he was apparently trying to assemble near a Kenyan primary
school before it hosted a presidential candidate's rally
exploded, police said on Sunday.
Residents heard a blast late on Saturday night in the
eastern frontier town of Garissa but police said they only
identified the site of the explosion caused by an improvised
explosive device (IED) at a primary school field on Sunday.
Martha Karua, the only female presidential candidate in the
March 4 vote and among the lower-ranked contenders according to
most polls, had been expected to speak at the grounds on Sunday
afternoon, regional police chief Charlton Mureithi said.
"Our initial assessment reveals the man was trying to set up
an IED near the dais, but killed himself as the device exploded
on him, ripping his body into pieces," Mureithi told reporters.
The open field also lies next to an army camp in a town used
as a support base for Kenya's military mission in Somalia.
There was no immediate claim of responsibility for the
intended attack, police said.
Karua kept her date with her supporters in the town but
spoke from a different venue.
"I would have loved to hold this gathering in the open place
where terrorists planted explosives last night," she told a
crowd, pledging to improve security if elected.
Kenya has experienced a spate of violent attacks, mostly in
the capital and close to the Somali border, since it sent
soldiers into its anarchic neighbour in October 2011 to drive
out al Shabaab Islamist rebels linked to al Qaeda.
The rebels have promised to retaliate and have launched
grenade and gun attacks that have raised concerns over how
secure the country is heading into the March 4 national
elections, the first since tribal fighting killed about 1,200
people following a disputed presidential vote in 2007.
Garissa, a market centre for trade in camels, donkeys, goats
and cattle some 200 km (120 miles) from the Somali border, has
borne the brunt of the attacks. The largely Muslim town has a
significant ethnic Somali population.
In October, Kenyan soldiers and Somali forces seized
Kismayu, al Shabaab's last big urban stronghold in southern
Somalia, driving the militants out.
"Its by the grace of God that the person who was planning
evil died. Many people would have lost their lives if that
mission succeeded," said Abdi Jama'a, a local resident.
