Hundreds of people are arriving in the Mozamican city of Pemba, mostly by boat, from areas attacked by Islamist militants last week, reports the independent TV station STV.
Residents' houses were destroyed in attacks in Mocimboa da Praia and Quissinga town last week.
Local leaders are quoted as saying on STV that around 250 families have arrived in the area.
Islamist militants, locally known as al-Shaabab, though with no known links with the Somali group of the same name, operate in the area.
