An explosion hit military vehicles at an intersection in the Turkish capital of Ankara.

Turkey’s president has vowed to continue its fight against terror attacks after a bomb blast in the country’s capital Ankara killed 28 people and injured dozens more.

According to reports, a vehicle full of explosives was detonated in rush hour as military buses were passing by in the city yesterday.

The UK Foreign and Common Wealth Office told British nationals to stay away from the area and to follow the instructions of local authorities.

It warned of further attacks, possibly against western tourists.

“The majority of attacks are likely to continue to target the Turkish state. Nevertheless, it is likely that some attacks will also target western interests and tourism, as they did in Istanbul on 12 January when 10 tourists died in a suicide bombing,” it said.

It said despite assurances from Turkish authorities that security has been tightened, further attacks could be indiscriminate and could affect places visited by foreigners.

“Border crossings into Syria and nearby locations have also been targeted. Be vigilant, monitor media reports and keep up to date with this travel advice,” the FCO said.

Earlier this month, TUI Group reported a 40% drop in summer holiday bookings to Turkey and Thomas Cook revealed it had cut its capacity to Turkey by 29% this summer.
