JAKARTA, Indonesia—The local Indonesian hotel owner obtained the insurance coverage for the JW Marriott and Ritz-Carlton properties that were attacked in deadly bombings early Friday morning, according to Marriott International Inc.

The blasts killed at least eight people and injured more than 60.

Both hotels—JW Marriott Hotel Jakarta and Ritz-Carlton Jakarta—are managed on behalf of local owners by Bethesda, Md.-based Marriott, said Bradley R. Wood, Marriott International’s senior vp-risk management. “The owners procure the insurance,” he said.

Additional coverage information was not available.

Mr. Wood said Marriott provides security for the hotels.

“The JW Marriott and Ritz-Carlton in Jakarta had extensive ongoing security measures in place, including four or five barriers outside the hotel, armed security personnel and magnetometers to enter the hotel,” he said. “Those security systems are recognized as among the most robust and state-of-the-art in the world.” He added that Marriott operations “already have loss-prevention leadership on the ground from our Asia-Pacific operations.”

“Immediately following the incident, police and hotel security responded and sealed off the area,” Marriott Chairman and Chief Executive Officer Bill Marriott wrote on his blog at the Marriott corporate Web site.

“Our guests at both properties were evacuated and moved to other nearby hotels,” Mr. Marriott wrote. “Both hotels sustained damage, but it does not appear to be structural. At the time of the incident, extensive security procedures were in place at the Ritz-Carlton and the JW Marriott.”

Atinç Yilmaz, president and chief executive officer of PT Marsh Indonesia, a unit of Marsh Inc., said the bombings came as a shock in a country that was enjoying a period of calm. Indonesia has not been badly affected by the financial crisis that has crippled other nations’ economies, Mr. Yilmaz said, and a recent presidential election ended peacefully. “Things have been going very well here. I was shocked when I heard about the bombings this morning” after landing in Jakarta on a flight from Turkey, he said.

“In the short term, some people may hesitate to come here because of this,” said Mr. Yilmaz, “but I don’t think it will heavily affect the country.”

But the attacks had immediate fallout as British soccer team Manchester United canceled plans to fly to Jakarta on Saturday for a match slated for July 20.
