NAIROBI, April 14 (Xinhua) -- Kenya's security agencies are on high alert over possible terrorism attack during or after the Easter holiday.

Police spokesman George Kinoti confirmed that security forces are on a high alert after receiving intelligence reports that nine terrorists are planning attacks

Kinoti also urged the public to adopt a higher level of vigilance ahead of the Easter festivities and in the coming month and report any suspicious activities.

According to a security report seen on Thursday, police said Kenyan suspects are moving back to the country following sustained attacks by the Kenya Defence Forces (KDF) and Somalia National Army in Somalia.

Police sources said some of the wanted terrorists have already made contacts with their relatives to seek for safe passage as they plan to disengage from the frontline in the battlefield to sneak to the country to launch attacks.

Mombasa County Commissioner Evans Achoki said security has been heightened in the tourism resorts in the coastal region to avert possible attacks by suspected Al-Shabaab militants.

"We have mapped the county and deployed security agents in area that might be soft target including the Likoni ferry and shopping malls," Achoki said.

Achoki said although the number of terror attacks have declined, terror threats remain real in the country.

"Though the number of attacks has drastically dropped, the militias have managed to launch some, more so in the border towns claiming tens of lives," said Achoki.

Kenya Defence Forces (KDF) under the African Union Mission in Somalia (AMISOM) have stepped up air and ground operations against the militants in southern Somalia despite their continued resistance, at times targeting military camp.

This week, KDF killed 15 Al-Shabaab terrorists in a security operation in West of Catamaa, Gedo region, Somalia.
