A second American has been confirmed killed in the weekend suicide bomb attack on the Marriott Hotel in Islamabad, hospital sources and diplomats said on Monday.
"We received the bodies of two male Americans, the Czech ambassador and one Vietnamese lady," said Wasim Khawaja, spokesman for PIMS hospital in the Pakistani capital.
Two diplomatic sources also confirmed that two Americans were killed in Saturday's attack on the Marriott, which killed at least 60 people and injured more than 260.
Czech ambassador Ivo Zdarek had been living at the hotel at the time of the attack. Officials in Prague confirmed his death on Sunday.
A Danish intelligence agent was still missing, Danish officials said on Sunday.
"What we have heard is that a Dane likely figures among the dead. If that proves to be the case, it would be profoundly tragic," said Denmark's foreign minister, Per Stig Moeller.
