Kenya's internal security minister says some refugees fleeing insecurity from neighboring countries have abused Kenyan hospitality by planning terror attacks against the country.

In an apparent reference to last month's terrorist attack on an upscale mall which killed more than 67 people, Joseph Ole Lenku said Friday among the remedial steps the Kenya government has taken to prevent a repeat attack is to start to repatriate Somali refugees.

Ole Lenku say refugees from war-ravaged Somalia make up the most of the 600,000 refugees in Kenya.

Al-Qaida-linked Somali militant group al-Shabab claimed responsibility for the Sept. 21 mall attack saying it was retribution for Kenya's troop involvement in Somalia. Ole Lenku says Somalia is now experiencing relative peace because of African Union troop intervention.
