The dead president's daughter visited his coffin on Sunday

He and 95 others, including many top defence officials and public figures, died when their jet crashed en route（在途中） to a war memorial service in Russia.

Other victims are being identified by relatives who flew to Moscow, where the bodies have been placed in morgues（陈尸所，太平间） .

Russian investigators² suspect pilot error caused the crash.

They say the pilots were warned that they were flying too low just before the plane clipped（剪除） tree-tops in heavy fog, as it was coming in to land at an air base on Saturday morning.

An outpouring（流露，倾泻） of grief has been seen in Polish communities across the world and the country is observing a week of public mourning. Monday is also a day of mourning in Russia, whose relations with its western neighbour were troubled for centuries.

Poland has moved to fill some of the gaps left by the disaster, appointing an acting³ head of the central bank, while the presidential post has been filled by the parliamentary speaker pending⁴（待定，悬而不决） a new election.

The Polish government plane was carrying dignitaries（高官，显要人物） who spanned Polish public life. They had been due to attend a memorial for the Polish victims of a World War II massacre⁵（大屠杀） by Soviet⁶ secret police at Katyn in Smolensk.

Commentators⁷ in Poland have stressed the irony⁸ that so many senior figures were killed making a visit to commemorate⁹ victims of a massacre which targeted the elite¹⁰ of Poland's officer corps¹¹.

"This is so very much like Katyn, where our head was cut off," said former President Lech Walesa.
