VIOLENT street crime is increasing in Venezuela's cities, particularly Caracas, Maracay, Valencia and Maracaibo, says the Foreign Office Travel Advice Unit (071-270 4129). Visitors are advised to be cautious after dark, and to use official taxi ranks (tickets can be bought at Caracas airport).

Travellers are also being warned of street crime in Mongolia. 'Visitors should remain vigilant and not travel alone off the main streets of any town. Wherever possible, use regular taxis. There has been an outbreak of meningitis type B: visitors should seek medical advice before setting off.'
