Phnom Penh, Nov 17 (IANS): Cambodia's three-day traditional Water Festival attracted more than 6.2 million spectators, the Ministry of Tourism said on Sunday.

The festival received an estimated 6.2 million local visitors and 52,498 foreign tourists during the three-day festival, the ministry said.

Cambodian Prime Minister Hun Manet said on Sunday that the Water Festival was conducted smoothly and joyfully while preserving the kingdom's unique tradition and culture, delighting both domestic and foreign tourists.

"This success was made possible thanks to the contributions from all relevant working groups, especially all kinds of security forces who had dedicated their time and physical energy to security, safety and public order for all festival guests," he said in a text posted on social media.
