Separately, in a message the President expressed profound grief and shock over the reports that over fifty Pakistani youth belonging to Quetta have gone missing at sea in East Java and called for a report from the concerned authorities.
According to media reports fifty five youth from Quetta went missing when the crew and captain of an Indonesian boat abandoned the ship leaving the Pakistani and other immigrants at the mercy of stormy sea during a heavy storm. More than 200 passengers including 55 Pakistanis are reported missing as the ship sank.
The President while expressing his grief and shock over the incident has also called for report from concerned authorities and an investigation into the circumstances under which the Pakistani youth undertook the hazardous journey, the spokesperson said.
