A Sindhi separatist outfit has claimed responsibility for twin blasts near Pakistan Rangers headquarters in the province that killed a soldier.
Police in Larkana town said that some pamphlets were found at the scene of the blasts which claimed the Sindhudesh Revolutionary Army (SRA) had carried out the attack.
The blasts yesterday killed a soldier and injured 15 people.
The pamphlet says the SRA has taken responsibility for the attack.
Senior police official in Larkana, Abdullah Shaikh said the pamphlets were being investigated but no one had been arrested in this connection so far.
"We don't know for certain whether what the pamphlets claim is true but once investigations are completed we will know the truth," he added.
The separatism movement in Sindh used to be a burning issue in the 1970s when G M Syed gave the call for an independent 'Sindhudesh' - a separate homeland for Sindhis but in the last two decades it has died down.
Although several nationalist parties exist in Sindh they remain in the framework of the political mainstream but police said the SRA was a different phenomena and indulged in militant activities and armed violence.
