A Japanese man, Kunio Hoshi, was shot and killed Saturday near Rangpur, in northern Bangladesh, five days after an Italian man, Cesare Tavella, was murdered in the capital Dhaka’s diplomatic zone, The Guardian reports. The Islamic State took responsibility for both murders.

Hoshi was killed in the Mahogany village, in the Rangpur district, by two masked gunmen riding a motorbike, who drove by and shot him three times, the Associated Press reports. A police official, Rezaul Karim, said that Hoshi had started a grass farm in Rangpur.

ISIS claimed responsibility for the killing on Twitter, according to the SITE Intelligence Group. In August, The Guardian reports, Bangladesh’s paramilitary agency arrested a British citizen and three others connected to the Islamic militant group over the killings of secular and atheist bloggers.

Several Western embassies have issued security warnings about militant attacks in the country. A security analyst at the Bangladesh Institute of Peace and Security Studies, Shafquat Munir, told The Guardian that no Western citizen had been targeted in Bangladesh for more than 10 years. However: “The groups in Bangladesh that have been in operation for many years have always been active and now, because of the rise of violent extremism worldwide, they are also upping their games,” Munir said.

“What is extremely alarming is they are able to pull off these attacks despite a supposedly high level of security. After the murder of Cesare Tavella, there was a warning. We would like to believe that the state of alert is quite high. My fear is that this is not going to stop. It will continue and it might escalate.”

Earlier this week, Cesare Tavella, an Italian aid worker, was killed in a similar attack, while working for a Netherlands-based church cooperative.
