二 | Canberra, Oct 18 (UNI) Australia has reversed a decision made four years ago to recognise West Jerusalem as the capital of Israel.
Canberra's decision in 2018 had undermined peace and put Australia out of step with other nations, Foreign Minister Penny Wong said. She stressed that Australia remained a "steadfast friend" to Israel. Its embassy will stay in Tel Aviv, the BBC reported.
At the time, Scott Morrison had said Australia would recognise West Jerusalem immediately but not move its embassy from Tel Aviv until a peace settlement was achieved. Morrison's government lost power in an election in May this year.
On Tuesday, Foreign Minister Penny Wong called the former government's decision a "cynical play" to win over Jewish voters ahead of an election in Australia.
"I regret that Mr Morrison's decision to play politics resulted in Australia's shifting position, and the distress these shifts have caused to many people in the Australian community who care deeply about this issue," she said.
She reaffirmed the country's "previous and longstanding" position that the status of Jerusalem should be resolved as part of peace negotiations between Israel and the Palestinian people. "We will not support an approach that undermines this prospect," she said.
The status of Jerusalem is one of the most contested issues between Israel and the Palestinians.
Former US President Donald Trump drew international criticism in 2017 when he reversed decades of American foreign policy by recognising the ancient city as Israel's capital. The US embassy was relocated from Tel Aviv to Jerusalem in May 2018.
Months later, then Australian Prime Minister Morrison announced his government would follow suit.
Israel regards Jerusalem as its "eternal and undivided" capital, while the Palestinians claim East Jerusalem - occupied by Israel in the 1967 Middle East war - as the capital of a future state, the BBC said.
The status of Jerusalem goes to the heart of the Israeli-Palestinian conflict.
Israeli sovereignty over Jerusalem has never been recognised internationally, and according to the 1993 Israel-Palestinian peace accords, the final status of Jerusalem is meant to be discussed in the latter stages of peace talks, the BBC added.
UNI ING。3-D打印样本长2.07米,重约7公斤。它是从三维打印构建的“冰淇淋”三维数据模型中恢复出来的。据报道,“奇奇”是世界上最长的圈养海豚。1980年被渔民捕获并送往水生栖息地。自从2002年它死后,没有人见过活海豚。

三 | 白鳍豚(学名:白鳍豚,lipotes vexillifer),又名:白鲸、白鳍、白旗、白夹、绿鳍、琵琶、中国鼠海豚、长江鼠海豚、长江河豚,是我国特有的淡水鲸种,只产于长江中下游。20世纪80年代,由于各种原因,海豚的数量急剧下降。2002年,据估计有不到50只海豚,被称为“水中大熊猫”。

四 | 海豚属于自己的家族,被列为国家一级保护野生动物和世界上12种最濒危动物之一。2007年8月8日,一份报告发表在《英国皇家学会生物学快报》上,正式宣布了海豚的功能性灭绝。
