Anklam bombed by the Luftwaffe on 29 April 1945

[Laurent Rizzotti]

I found on German wikipedia (for what it is worth) a page called "Luftangriffe auf Anklam". It says that after Anklam was taken by the Soviets on 29 April 1945, it was bombed by the Luftwaffe the same day. Here is my translation:
"The Luftwaffe carried out a devastating bombing attack. Mainly incendiary bombs were used, which further increased the degree of destruction of the city (among other things, the old Rathaus on the Peene was bombed) and killed over 370 people."

I highly doubt that Luftwaffe would deliver such a powerful air attack on Anklam at this stage of the war. Most of the flying then was done by German fighter-bombers. Also the number of killed is very high (close to the 400 reported killed by 100 B-17s on 9 October 1943). Maybe it includes all dead of the period, including the victims of ground battles, artillery fire and so on.

So my question: has someone a more serious source describing this Luftwaffe raid on Anklam ?
