NAIROBI, June 19 (Xinhua) -- Kenya's security officers said Monday they have arrested 88 terror suspects in Nairobi for plotting to carry out attacks during Eid celebrations marking the end of the Muslim holy month of Ramadan.

A police report says the suspects, 15 foreigners and 73 Kenyans, were arrested on June 15 at a rehabilitation center in Nairobi's Eastleigh residential estate that is largely inhabited by ethnic Somalis, in a joint security swoop.

"A joint security operation between anti-terrorism police unit, flying squad and directorate of criminal investigations (CID) acting on intelligence report raided the centers which are suspected of radicalization and human trafficking," the police said.

The East African nation has faced insecurity as bomb attacks using improvised explosive devices and grenades have been hurled in northeastern region since soldiers entered Somalia in 2011 to secure the shared border.

Kenya has also warned that attacks as threatened by the Somali-based terrorist group Al-Shabaab could affect the country's risk profile, scaring away foreign investors and tourists.

Meanwhile, the police are also interrogating four terror suspects at the weekend for plotting to carry an attack during Eid celebrations.

Three suspects were arrested in Voi town while escaping to Nairobi and another suspect was arrested in Nairobi and is yet to be airlifted to Mombasa to face similar charges.
