Police said on Friday a third bomb was found and defused in a laptop computer bag on the 18th floor in Marriott Hotel, Jakarta in Indonesia.

Room 1808 had become their post since the 15th (of July), National police chief General Bambang Hendarso Danuri said at news conference.

Suicide bombs ripped through two luxury hotels, the Marriott and Ritz-Carlton in the capital of Indonesia on Friday, killing at least nine people and wounding 50 as guests sat down for breakfast, police said.

The search for more explosive devices is continuing at the two hotels and in surrounding areas.

Police said the bombers had checked in to the Marriott as paying guests on Wednesday and had assembled the bombs in their room.

I am sure most of us are deeply concerned, feel very sorry and are crying silently, like the way I am feeling, said the president Susilo Bambang Yudhoyono.

They do not have a sense of humanity and do not care about the destruction of our country, because this terror act will have a wide impact on our economy, our business climate, our tourism, our image in the world and many others, the president added.

The explosions on Friday are the first major terrorist attacks in Indonesia since October 2005, when suicide bombers killed 20 on the popular tourist island of Bali.
