KUALA LUMPUR: A French satellite scanning the Indian Ocean for remnants of a missing jetliner found a possible plane debris field containing 122 objects, a top Malaysian official said Wednesday, calling it "the most credible lead that we have."

Meanwhile, frustrated relatives of Chinese passengers aboard missing the missing flight demanded answers from the Malaysian ambassador for a second consecutive day Wednesday, with some mocking him at a Beijing hotel.

“All the things that were promised, we have received nothing. Was Mr.Yahya talking out of the other end of his body — was he talking out of his arse?” one relative said, referring to Malaysia Airlines Group CEO Ahmad Jauhari Yahya.

His comments drew applause from other family members, querying why some of the help previously provided by Kuala Lumpur to the families in Beijing had been withdrawn.

Ahmad Jauhari previously said the company had deployed more than 700 “dedicated caregivers” to support the next of kin, as well as financial assistance.

The Ambassador, Iskandar Sarudin, explained that Malaysian administrators had been withdrawn from the hotel at the request of Chinese authorities as “emotions had been running high” after Prime Minister Najib Razak said satellite data suggested the flight had gone down in the southern Indian Ocean.

But his words did little to soothe the angry relatives and some accused him of having “unfounded” prejudices against Chinese people.

We have a saying in China,” one of the relatives said to him. “Judging noble people with the mentality of cowards.”

Another asked him sarcastically: “Sir do you have a problem with your vision,” as he offered to show him a picture of a lock on a door of a room in which support staff were supposed to be based.

Two-thirds of the 239 people on board the missing aircraft are Chinese citizens. The showdown at Beijing’s Lido Hotel came a day after scores of emotional family members descended on the Malaysian Embassy, linking arms and denouncing Kuala Lumpur after Najib’s announcement.
