At least six members of the Turkish security forces have been killed in the eastern city of Tunceli when the vehicle was destroyed by a powerful explosion. A civilian was also killed. James Reynolds reports from Istanbul.

Shaky TV pictures broadcast on Turkish TV show two vehicles burning on a mostly deserted road in the city of Tunceli. A group of men uses a hose to try to put out the fires. Reports say that one of the vehicles was carrying explosives and detonated as the other vehicle an armourer truck carrying soldiers went by. Here in Turkey the automatic suspicion is that the explosion was the work of the Kurdish separatists of the PKK. Since June 2011 more than 700 people in Turkey have been killed in fighting and bomb attacks.

Police in Madrid have ringed the Spanish Parliament as thousands of mainly young protesters try to march in the building to express anger at the government's ever stricter austerity programme. Riot police fired rubber bullets and used batons to force back demonstrators trying to break down the cordon placed around the parliament building. The protests came ahead of next year's budget presentation on Thursday which is expected to propose even deeper cuts in wages, and government services. Tom Burridge was at the demonstrations in Madrid.
