Several police officers died in an ambush claimed by the militant group al Shabab on Monday evening in Yumbis village, north of the city of Garissa in Kenya, the Standard and Daily Nation newspapers reported.
Al Shabab attacked Yumbis and hoisted their flag on a mosque where they held prayers before heading to another nearby village.
In an attack on a university in Garissa last year, 148 students were massacred by the militant group.
A police spokesman, George Kimoti, confirmed there was another attack in the Garissa region but declined to give more details.
"Please give us time to consolidate all the information," he said.
The police officers were on their way to rescue another team wounded earlier on Monday. They were reportedly moving in a convoy of four vehicles when the militants attacked them.
Al-Shabab has recently carried out several attacks in Kenya in retaliation for Kenya's military involvement in Somalia, where Kenyan troops are part of an African Union force bolstering the Western-backed central government.
Despite major setbacks in 2014, al-Shabab continues to wage a deadly insurgency against Somalia's government and remains a threat in the East African region.
