MOSCOW, July 21 (Reuters) - The Caspian Pipeline Consortium has stopped receiving oil from Kazakhstan following the suspension of loadings due to attacks on oil tankers at its Black Sea terminal, three industry sources said on Tuesday.

Two of the sources also said that oil reservoirs at the terminal are full.

CPC, which accounts for 80% of oil exports from Kazakhstan, declined to comment.

CPC said on Monday that oil loadings were suspended at the Black Sea port following a Ukrainian drone attack on tankers.

"Chevron continues to monitor the situation at CPC. The safety and security of personnel remain our top priority. Any further inquiries regarding CPC should be directed to that entity," Chevron CVX.N, which has a 15% stake in CPC, said in an emailed comment.

The suspension of loadings from the CPC pipeline, which exports almost 2% of global oil, adds to global oil concerns as the war in Iran has already disrupted supply from Saudi Arabia and other Gulf producers.
