DHAKA, July 4 (Reuters) - At least 10 people were injured when farmers demanding fertiliser clashed with officials and burned and damaged three administrative offices in Bangladesh on Wednesday, police said.

About 5,000 farmers became angry after a state-managed agriculture office in Cahpainawabganj district, 350 km (219 miles) north of Dhaka, failed to supply them with enough fertiliser at a controlled price.

Aurthorities called in troops and paramilitary forces to help bring the situation under control, police said.

Mainly agrarian Bangladesh, which produces about 26 million tonnes of rice annually, often faces shortages of fertiliser, much of which is imported.

In early 1990s, several farmers demanding fertiliser were shot dead by police during clashes.
