Silicon Diode problem

Im having trouble figuring how to find the current in the diagram below.

What is the voltage across R1?

Im not sure is it 10-0.7=9.3v?

Definitely not.

The voltage across components that are in parallel is always the same, therefore V(R1)=V(D2)= ?
The voltage across components that are in series add up, therefore V(D1)+V(R1)+V(R2)= ?

Hint: Kirchhoffs laws apply.

You obviously know that D1 drops 0.7V when conducting. Quite correct.
So what voltage will D2 have across it when conducting?
