Tunisia began deploying armed police to protect foreign tourists on Wednesday after last week's deadly jihadist attack on a beach resort, the interior ministry said.
AFP correspondents saw no increased security at tourist sites they visited during the morning but a ministry spokesman said the deployment was beginning with hotels and seaside resorts.
"This morning, we started to deploy and armed police will be in hotels within the hour," spokesman Mohamed Ali Aroui told AFP.
Security officials "are busy deploying at Hammamet," a seaside resort in the south of Tunis, he added.
Tunisia promised a raft of new security measures after last Friday's rampage in the resort of Port El Kantaoui, which killed 38 people, most of them British tourists.
It said it would deploy 1,000 armed officers from Wednesday to reinforce the tourism police, who would also carry guns for the first time.
At the site of ancient Carthage outside Tunis on Wednesday morning, AFP correspondents saw no police at the Antonine Baths and just one guard at the Carthage Museum.
At the upmarket seaside resort of Gammarth, home to five hotels, security guards said they were aware of plans for a new deployment, but said no one had yet arrived.
