US Assistant Secretary of State for South and Central Asian Affairs Robert O Blake will visit Sri Lanka from August 29-31, 2011, the U.S. Department of State said.

During his stay in Sri Lanka, he will meet with high ranking government officials, civil society representatives, university students and political leaders.

Probes into killings during the last stages of the war between the government forces and the LTTE need to be investigated, preferably by the government of Sri Lanka and its own institutions, he said recently in an interview to AFP.
