Ukrainians protest over gas hike
Ukraine is dependent on Russia for most of its gas
Tens of thousands of people have protested in the Ukrainian capital, Kiev, against plans to sharply raise gas and electricity prices.
A BBC correspondent in Kiev said the protests were as big as those during the 2004 Orange Revolution, which swept President Viktor Yushchenko to power.
Consumers face a near doubling of gas and electricity prices from 1 July, Ukraine's trade unions say.
Russia doubled the price of gas supplies to Ukraine earlier this year.
