Prime Minister Manmohan Singh on Friday visited victims of the blasts in suburban trains who are being treated at Sion and King Edward Memorial hospitals in Mumbai.
The prime minister went around various wards at both the hospitals. He asked the injured about their condition and the treatment they were being given, hospital officials said. He was moved by the plight of the injured, they said.
Dr Singh was briefed about the medical aid being given to the blast victims by the deans of both hospitals.
The prime minister was accompanied by Maharashtra Governor S M Krishna, Maharashtra Chief Minister Vilasrao Deshmukh, Union Home Minister Shivraj Patil, Union Agriculture Minister Sharad Pawar and top state government officials.
Dr Singh arrived in Mumbai on Friday afternoon and drove first to Sion Hospital and then to KEM Hospital, where many of the injured were taken following Tuesday's seven deadly blasts in commuter trains during the evening rush hour.
"I have heard from the patients. Some of them became very emotional, but they have nothing but gratitude for the hospital staff," Dr Singh told reporters.
"I take this opportunity to thank the members of the medical fraternity -- doctors, nurses, paramedics -- for the splendid job they have done during this hour of great tragedy."
Hospital officials said Dr Singh was moved by the plight of the injured.
"I have assured all the patients that the best possible medical assistance will be made available so that they can recover most speedily and re-start their normal lives," Dr Singh said.
Later, the prime minister is to interact with state government officials to take stock of the situation in the wake of the terrorist attacks that killed 200 people and injured over 700.
Dr Singh is scheduled to address the media before leaving for Delhi later in the day.
