China expressed condolences Tuesday to the three South Koreans who were killed in a suspected terror attack in Egypt's Sinai.

At least four people, including three South Koreans and the Egyptian bus driver, were killed in the bombing attack on a bus filled with South Korean churchgoers in the Sinai Peninsula on Sunday.

"We are saddened by the tragic event," China's foreign ministry spokeswoman Hua Chunying told reporters during a daily press briefing.

"We express condolences to the victims and sincere solicitude to their families," Hua said. "We believe that the ROK (South Korea) and Egypt will appropriately deal with the relevant matter through consultations."

The South Korean churchgoers were on a 12-day pilgrimage to Turkey, Egypt and Israel.

Though some officials said the body of the suspected suicide bomber was found on the scene, a statement posted on militant websites claiming responsibility for the attack made no mention of the perpetrator being dead. The statement purports to be from an al-Qaida-influenced group called Ansar Beit al-Maqdis. Officials in Seoul said it was not clear if South Koreans were specifically targeted in the attack.
