Islamabad: At least 20 bomb blasts hit cities in Pakistan's southern province of Sindh yesterday that targeted and damaged ATM outlets of government-run banks, killing one person and causing panic, police and media reports said.

Four explosions occurred in Hyderabad — some 140 kilometres northeast of the provincial capital Karachi — the second largest city of the province while similar blasts were reported from different other towns including Nawabshah, Larkana and Dadu.

"The dead person was a security guard of a private bank while two other got minor injuries," Ayyaz Mahmoud, a police official said.

Police said pamphlets bearing the name of a separatist outfit calling itself Sindhu Desh Liberation Army were found near the targeted ATMs in Hyderabad.

Reports said a similar blast damaged a railway track near the town of Ghotki causing suspension of train traffic for sometime.

No one took responsibility for the blasts but Sindhi nationalists have carried out similar attacks before.

Last year a number of minor explosions targeted railway lines at different places and the group had claimed responsibility for the acts of sabotage.
