British travellers to Kenya have been urged to remain vigilant at all times following deadly blasts over the weekend.
The Foreign and Commonwealth Office reinforced its travel advisory in the wake of two explosions on buses travelling from the capital of Nairobi on Sunday.
This followed twin explosions in Mombasa on Saturday which killed at least three people.
One involved a grenade reportedly thrown onto a bus and another was at a beach bar near the Nayali Reef Hotel, although there were no reports of casualties there.
The blasts were the latest in a string of explosions since a major terrorist attack on the Westgate shopping centre in the Westlands district of Nairobi.
