A Bangladeshi court has issued arrest warrants for former Prime Minister Khaleda Zia and 27 other opposition party leaders on accusations they instigated an arson attack on a passenger bus during an anti-government protest last year.

Dhaka Metropolitan Sessions Judge Kamrul Hossain Mollah made the order Wednesday after accepting the charges pressed by detectives that Zia instigated the violence when she asked her supporters to enforce a blockade to remove the administration of Prime Minister Sheikh Hasina.

Defense lawyers argued the case was politically motivated and the accused were not involved in any violence.

The Jan. 23 attack on a bus in Dhaka killed one person and injured 30.

The judge asked police to report to the court on April 27 on what has been done to execute the warrants.
