DHAKA: Police on Wednesday charged Bangladesh’s main opposition chief, Khaleda Zia, with masterminding arson attacks during deadly anti-government protests last year, a day after the execution of one of her key political allies. Police said they had brought charges against Zia, a two-time former prime minister, and 27 officials from her Bangladesh Nationalist Party (BNP) for their roles in the fire-bombing of two buses in the capital Dhaka. “We’ve submitted charge sheets against 27 people including Khaleda Zia to the Chief Metropolitan Magistrate Court,” local police chief Mohammad Selimuzzaman told AFP. “She has been charged as a mastermind in the arson attacks.” It came hours after the execution of Zia’s main political ally, Jamaat-e-Islami party leader Motiur Rahman Nizami, for war crimes committed during the country’s 1971 independence conflict with Pakistan. His hanging late Tuesday sparked several outbreaks of violence and heightened tensions in the Muslim-majority country, already reeling from a string of killings of secular and liberal activists. Zia, a bitter political rival of Prime Minister Sheikh Hasina, is already on trial for corruption in a long-running case. She also faces around half a dozen other charges stemming from her tenure as the premier of the country from 2001-06 — charges she rejects as baseless and politically motivated. There was no immediate comment from Zia on the latest allegations, which relate to fire-bombings in Dhaka’s Darussalam neighbourhood in March 2015, which caused no injuries or deaths. Earlier this year Zia was charged over a separate deadly fire-bombing of a bus in Dhaka during a nationwide transport blockade she ordered last year in an effort to topple the government. The blockade unleashed a wave of bloody violence, leaving more than 120 people dead as opposition activists fire-bombed hundreds of buses and trucks, and police responded by firing live rounds.
