Islamister, høyst sannsynlig Al-Shabaab, har drept minst 48 mennesker i havnebyen Mpeketoni i Kenya.
Boko Haram og ISIS’ metoder ser ut til å ha en smitteeffekt.
Massakren vil ha en helt ødeleggende virkning på turiststrømmen til Kenya.
Krigerne kom i 21-tiden søndag kveld og holdt på i fem timer, uten at politi eller hær var synlige.
At least 48 people have died after suspected Islamist militants attacked hotels and a police station in a Kenyan coastal town, officials say.
Witnesses in Mpeketoni said gun battles went on for several hours and reported seeing buildings set on fire.
The town is on the mainland near Lamu island, a well-known tourist resort.
Kenya has suffered numerous militant attacks since 2011 when its forces entered neighbouring Somalia to combat al-Shabab fighters.
This is the most deadly attack in Kenya since at least 67 people were killed during a siege at Nairobi’s Westgate shopping centre last September.
The BBC’s Yusuf Dayo in Nairobi says the attack started at 20:30 local time (17:30 GMT) on Sunday as locals were watching a football World Cup match on television.
Local residents told the BBC the gunmen hijacked a van and used it to attack various locations across Mpeketoni, which tourists pass through before crossing to Lamu.
Witnesses said gunmen, who had their faces covered, threw explosives into the local police station before entering and stealing weapons.
District deputy commissioner Benson Maisori said several buildings in Mpeketoni had been burned down, including hotels, restaurants, banks and government offices, AFP news agency reports.
Bozo Jenje, a journalist in Mombasa, told the BBC that residents had reported seeing bodies scattered across roads in the town.
Local resident John Waweru, 28, said two of his brothers had been killed.
«The attackers came in around 9pm. I heard them shouting in Somali as they fired around. I lost two of my brothers, and I escaped. I ran and locked up myself in a house,» he told AFP.
Questions are being asked about how gunmen could raid a town for about five hours without an adequate response from the security forces, she says.
Volden har eskalert kraftig. I september 2011 ble ekteparet Tibbutt overfalt i sitt hjem på den fjerntliggende øya Kiwayu, nord for muslimske Lamu. De skjøt mannen, David på 58, og bortførte Judith. Etter seks måneder ble hun løslatt mot løsepenger.
Judith ble intervjuet på BBC. Hun sa Kiwayu hadde vært deres hjem i mange år, de følte seg helt trygge. Så dette.
I september 2013 slo al-Shabaab til mot Westgate shoppingsenter. 67 ble drept av krigerne, hvorav en hadde bodd i Norge.
Amerikanske og britiske myndigheter hadde tipset om at al-Shabaab hadde planer om et angrep. Men Kenya har ikke ressursene til å forsvare seg på fjerne steder som Mpeketoni.
