Two more people have died after a hand grenade was thrown into a Kenyan bar where patrons were watching a Euro 2012 football match, the Red Cross says.
Police earlier said that one person had been killed in the blast at the Jericho bar in the resort town of Mombasa.
One of the 30 people injured is being held as a suspect, police say.
The blast comes a day after the US embassy had warned that there was an "imminent threat" of a terrorist attack in the area.
Earlier this week, Kenyan police arrested two Iranian nationals over suspected links to a network planning attacks in Mombasa.
Police also said they had recovered suspected bomb-making material in the capital, Nairobi, on Saturday.
The explosion happened at around 22:00 local time (19:00 GMT) on Sunday, a police source told the AFP news agency.
The bar was busy with people watching the quarter-final match between England and Italy in the Euro 2012 football tournament, witnesses said.
Along with the US, France's embassy in Nairobi had also warned its citizens to be "extremely vigilant" in the area.
US officials had also been told to avoid the area until 1 July.
In May one person died after explosive devices were thrown into a nightclub in Mombasa.
Kenya has seen a number of grenade attacks since sending troops into Somalia last year to fight the Islamist al-Shabab militia.
Earlier this year, the African Union force backing Somalia's interim government was boosted from 12,000 troops to nearly 18,000 to incorporate the Kenyan troops.
