Spain and Portugal have seen an increase in bookings from British holidaymakers for summer amid fears of terror attacks at other traditionally popular locations, travel agents have said.

The Association of British Travel Agents (ABTA) is warning that people leaving it late to book their trips to the two destinations may find it more difficult than usual due to "notable increases" in reservations.

They are being advised to consider alternative places within the countries such as the northern coasts of Spain and Portugal, or travelling outside the peak months of July and August.

Demand for destinations such as Egypt and Tunisia has dropped following terror attacks in those countries in 2015, the organisation said.

In June, a gunman targeted holidaymakers at the beach resort of Sousse, killing 38 people, including 30 Britons.

So-called Islamic State claimed responsibility for the attacks.

A Russian passenger plane was also brought down by a bomb in Egypt's Sinai peninsula in October 2015, killing all 224 people on board.

ABTA chief executive Mark Tanzer said the organisation is seeing a significant increase in summer holiday bookings to western Mediterranean destinations.

He is urging holidaymakers who are looking to travel not to delay in making their booking.

Tunisia's ambassador has called on the Foreign Office in the UK to relax its travel advice on Tunisia, after tourism to the country fell by 90%.
