In Dhaka, Bangladesh, clashes between security forces and protesters have left one police officer dead and 100 demonstrators injured.
The demonstrators led by opposition activists were protesting a British firm's plans to construct a coal mine in Phulbari north of Dhaka.
Protesters threw rocks and clashed with police and police used batons to disperse them.
Protesters say the mine will displace hundreds of families and damage the environment. A spokesman for the firm denies there will be any environmental problems.
The main opposition party had also called for a strike which closed schools and shops in the capital and disrupted traffic on Wednesday in Dhaka.
On Monday, activists set fire to buildings linked to the firm at the coal-mine site, and six people were killed during a demonstration two days earlier.
