"Investigations should be prompt and those found to be responsible must be brought to justice in accordance with international standards of fair trial, regardless of their position or political affiliation," the UK-based international human rights watchdog said.

In a statement issued yesterday from its headquarters, the AI mentioned that a number of individuals, armed with rocks and bricks, violently disrupted the rally allegedly on the instigation of a ruling BNP lawmaker.

"While a limited number of local police were at the scene, they reportedly did little to protect the journalists, many of who were badly injured," the statement said.

The rally was held to protest the recent harassment of four Kushtia-based journalists who had been accused of extortion by a BNP MP after they made reports on upcoming election. The case led the four to flee the area.

The AI also said printing of a local daily newspaper, Dainik Andoloner Bazar, is reported to have been suspended on the instigation of the same BNP lawmaker.

"Amnesty International calls on the Government of Bangladesh to take effective measures to investigate all allegations of intimidation and violent attacks on journalists in Kushtia," the statement said.

It further said as campaigning begins for the 2007 national elections, the AI believes that it is particularly important for all citizens to be able to peacefully exercise their right to freedom of expression and opinion without fear of intimidation or harassment.

"Amnesty International recognises that journalists, through accurate and objective reporting, play a pivotal role in allowing all citizens to enjoy their right of access to information," the statement added, calling on the Bangladesh government to ensure this role remains protected.
