MOMBASA: Kenyan police arrested a suspected Al-Shabab fighter in Mombasa on Tuesday and recovered weapons that had been intended for use in aborted New Year’s Eve attacks on the coastal city, a senior government official said.

Mombasa County Commissioner Nelson Marwa told a news conference that four other suspects had escaped the raid, including two militants from the Somali-based group wanted for major attacks on Kenya since 2013.

“These men are behind major plots for attacks in the country and are linked to the Garissa University and Lamu attacks,” Marwa said.

“They had planned to attack public beaches in Mombasa during the New Year when there were many people, but they were deterred by the level of security we had mounted there.”

Al-Shabab killed 148 students in the attack on Garissa University last April. In June 2014, the group killed 65 people over a 24-hour period in and around Mpeketoni in Lamu county, also in Kenya’s east. It was also responsible for a raid on Nairobi’s Westgate Mall in 2013 that killed 67 people.

Kenyan authorities have circulated pictures of suspected al Shabab militants and offered a 2 million shilling ($19,569.47) reward for information leading to arrests.

Al Shabab seeks to overthrow the Western-backed Somali government. It has frequently attacked neighboring Kenya in recent years, saying it is retaliating for Kenya’s participation in an African Union peacekeeping force in Somalia.
