East African Legislative Assembly (EALA) MP Kanini Kega has claimed he narrowly escaped an armed attack after unknown gunmen allegedly chased his vehicle and opened fire.

In a video shared on Monday, the former Kieni MP said he and members of his team fled the alleged attackers and sought refuge in a nearby house, where they remained temporarily safe.

"Kenyans, you can see I'm under attack. I have been chased and they pointed guns at me and we have managed to escape. They have sprayed my vehicle. I'm only alive by the grace of God. We are not going to relent on the fight," Kega said.

He said they had taken shelter in a house as they assessed the situation.

"We are temporarily safe in this house," he added.

Kega did not say where or when the alleged attack occurred, and there was no immediate statement from police on the incident.

His claims come amid heightened political tensions following violent incidents in Kisumu and Nyahururu over the weekend.

Speaking on Monday, Interior Cabinet Secretary Kipchumba Murkomen said security agencies were intensifying efforts to curb political violence and goonism, warning that politicians found to be inciting violence or threatening national security would face arrest.

"There are people saying we should arrest politicians. We will arrest them. When we get enough evidence we will arrest them for sure," Murkomen said.

The CS said more than 20 suspects had been arrested over Sunday's incidents in Kisumu and Nyahururu and urged the Judiciary to impose stiff penalties on those found guilty.

"Let's not start pretending like the police are not doing anything about this. Over 20 people have been arrested so far in connection to yesterday's incidents. We must work with the Judiciary. When we arraign these suspects, the courts should take tough legal action commensurate to their offences," he said.

Murkomen also assured residents of Ol Kalou of adequate security ahead of Thursday's by-election, saying the government had put in place sufficient measures to enable the Independent Electoral and Boundaries Commission (IEBC) to conduct a free and fair poll.

His remarks came a day after violence outside ACK St Stephen's Cathedral in Kisumu, where Siaya Governor James Orengo and Nairobi Senator Edwin Sifuna had attended a church service.

Police said one person was killed and 14 suspects arrested following the unrest.

In Nyahururu, police arrested six suspects after armed groups allegedly disrupted a political event organised by the Linda Mwananchi movement by throwing stones at worshippers attending a church service at AIPCA Nyahururu Cathedral, injuring several people.
