Prague - The Czech government Sunday condemned "the terrorist attack" on a five-star hotel in Islamabad which killed more than 50 people, including the Czech ambassador.

"The Czech Republic sharply condemns any type of terrorist activities," Czech Prime Minister Mirek Topolanek said in a statement.

Czech Ambassador to Pakistan, Ivo Zdarek, was identified as one of the victims of Saturday's suicide bombing that left at least 53 dead and many more injured, Pakistani and Czech officials confirmed.

The 47-year-old diplomat had stayed in the Marriott temporarily because his residence was undergoing refurbishment and a security upgrade, said Zuzana Opletalova, a spokeswoman for the Czech Foreign Ministry.
