Police in Bangladesh say they have detained nine people following the murder of a newspaper editor in the south-western city of Khulna.
Humayun Kabir, editor of the Bengali daily Janmabhumi, was killed by a bomb on Sunday - the latest in a series of attacks on reporters in the region.
Journalists across the country condemned the killing and demanded greater protection.
An outlawed extreme left-wing group said it carried out the attack.
Death threats
Mr Kabir died in hospital after unidentified assailants threw two bombs at him in front of his office.
His son survived the attack with minor leg injuries.
Manik Saha was killed in another bomb attack in January

The BBC's Waliur Rahman in the capital, Dhaka, says the government has promised to act quickly to identify the killers and bring them to justice.
Mr Kabir is the latest journalist to be killed in the country's south-west. Twelve others have died over the past decade.
In January this year, senior journalist Manik Saha, a regular contributor to the BBC Bengali service, was killed in a similar bomb attack in Khulna, 140km (85 miles) south-west of Dhaka.
Journalists in Bangladesh often face death threats for reporting on affairs such as corruption, political violence or organised crime.
Mr Kabir's newspaper has published articles on organised crime in the city.
Journalists nationwide wore black badges on Monday in memory of Mr Kabir.
Media unions in Khulna are planning a general strike there for Tuesday in protest at the killing.
