Three people have died and at least 10 have been wounded after gunmen opened fire in a church outside Kenya's coastal city of Mombasa.

The three gunmen opened fire inside the Joyland Church in a Mombasa suburb of Likoni, killing two people, Kenyan officials said on Sunday, while a nurse at a nearby hospital reported a third person had died while being treated.

Kenya has suffered dozens of small attacks, many on churches, over the last several years. Muslim-Christian tensions on Kenya's coast are high.

Sunday's shooting comes about a week after police on the coast intercepted a car packed with explosives police believe were to be used for an attack.
