A survivor of the German concentration camp in Sobibor says he recognises John Demjanjuk as one of the guards at the camp.

An 87-year-old Ukrainian, Alexei Vaitsen, told a Munich court he recognised the former guard from photographs. He is the first witness to recognise the defendant.

Mr Demjanjuk is now 89 years old and on trial in Germany for war crimes. He is accused of involvement in the deaths of 28,000 Jews during the World War Two.

The trial has been adjourned a number of times due to his poor health.

It is uncertain whether more witnesses will be heard in the case.

In 1988, Mr Demjanjuk was sentenced to death by an Israeli court. The court identified him as the guard known as "Ivan the Terrible" at Treblinka concentration camp. The verdict was overturned at appeal when fresh evidence identified someone else as "Ivan the Terrible".
