The Islamic State (Isis) has claimed that it has killed an Italian citizen in the Bangladesh capital Dhaka.

Cesare Tavella, 50, was shot dead on Monday night in the diplomatic quarter in Dhaka by gunmen on a motorcycle, according to the Dhaka Tribune

The Isis claimed responsibility for the murder through an online statement.

The Italian citizen was in Bangladesh to work with a charity on food security and he was probably targeted for being a Westerner. He was shot thrice and succumbed from injuries to his abdomen. 

If it is verified to be an Isis attack, it will be the first such attack by the terror group in the Islamic nation in South Asia.

"Three men riding on a motorbike shot him and fled," a witness was quoted saying by Reuters. 

The spate of Islamist and murders in Bangladesh forced the Australian cricket team to delay their travel to the country for matches starting 3 October.

The UK government has also reportedly issued an alert to its nationals living in Bangladesh following increasing terror threats.
