| At least eight people have died in a blast in a Russian market, in what officials believe was a deliberate attack. The explosion in the central city of Samara was initially blamed on an accident with gas canisters. But prosecutors later said plastic explosive was used, although it was not clear whether a terror attack or a business dispute was suspected. Nearly 40 people were injured in the blast in the crowded Kirov market at noon (0700GMT). Television pictures showed scenes of devastation, with bodies lying among wrecked market stalls. The city is 800km (500 miles) south-east of Moscow. |
