MANILA, Nov 27 (Reuters) - An earthquake shook the Philippine capital Manila and other cities on the main Luzon island on Tuesday, disrupting suburban train services and causing some people to flee high-rise buildings.

There were no immediate reports of casualties.

The United States Geological Survey said the epicentre of the 6.0 magnitude was 195 km (120 miles) northwest of Manila, in the Luzon Sea. It was at a depth of 62 km (40 miles).

People ran out of offices and homes in Manila and in the northern city of Baguio, witnesses said. Children were evacuated from schools.

The Manila suburban train service was disrupted and commuters walked on the tracks to the nearest stations, witnesses said. (Reporting by Rolando Ng, Carmel Crimmins and Raju Gopalakrishnan; editing by David Fogarty)
