A fire has broken out at Europe's tallest freestanding structure - the Ostankino Television Tower in Moscow.
Firefighters have been battling the blaze at the rocket-like 540m-tall building, which was designed by Russian architect Nikolai Nikitin.
Russian media reported that the fire may have broken out after sparks from welding work set light to insulation in the 40-year old building.
The fire is the second disaster to befall the tower in recent years. In August 2000 three people died when flames tore through the structure, which is twice as tall as the Eiffel Tower.by Max Thompson
