Doctors will now try to remove the bullet to save the 10-month-old baby's life, a BBC correspondent says.

Doctors believe the same bullet which killed his mother, while she was shielding him, exited her body and buried itself in his head.

Six people died in the attack.

No group has said it carried out the raid, but officials have blamed Somali Islamist militants for similar attacks.

Baby Satrin Osinya was accompanied by his father when he was flown by the emergency services to Nairobi's Wilson airport, the BBC's Idris Situma reports from the scene.

Doctors at Nairobi's main medical facility, the Jomo Kenyatta Hospital, will see if it is possible to remove the bullet.

'Escaping on foot'

Medical staff at the Coast General Hospital in Mombasa said the baby had been in great pain and doctors were not sure whether the bullet could be removed without inflicting more damage or risking his life,Kenya's privately owned Standard newspaper reports.

"The young boy has not slept the whole night because of pain and has been conscious throughout," an unnamed nurse is quoted as saying.

Kenyan police say the attack on the church in Likoni could have been an "act of terrorism".

At least two gunmen burst into the church and started shooting indiscriminately.

The attackers managed to escape on foot before police arrived.

Blood-soaked Bibles and overturned chairs lay strewn across the church's floor after the shooting.

Security has been stepped up in the area in recent days following the arrest of two men last week who police said had bombs hidden in their car.

There have been several incidents of violence in Mombasa in recent months, involving the security forces and Islamist militants.

The al-Qaeda group al-Shabab has carried out several attacks in Kenya since 2011, when Kenya sent troops into Somalia to battle it.

Last year, at least 67 people were killed after al-Shabab militants took control of the Westgate shopping mall in the capital Nairobi for four days.
