The bodies of two sisters who drowned after their boat collided with a Vietnamese fishing vessel were recovered at sea on Saturday, according to police.

The sisters, Ev Sokbhom, 43, and Ev Sakhorn, 35, went fishing near the Vietnamese border in the wee hours of Thursday with an unidentified man, said Hanh Kea, police chief of Kampot province’s Kampong Trach district.

The boat, which had no lights on, was hit, causing the three to fall overboard.

“Their boat was so dark, which caused the Vietnamese boat to hit it”, Kea said.

While the man was saved by the Vietnamese fishermen, the sisters, who could not swim, sank and drowned.

Their family did not file a complaint, but were given 300 million dong (almost $15,000) by the owner of the Vietnamese boat.

Kea said he often told fishermen to be more careful.

“Some listened to me and some are still careless with their job.”
