JAKARTA (REUTERS,AFP) - Indonesia will execute 14 drug convicts including at least four foreigners this weekend, the attorney general said on Wednesday (July 27).

Those executed will include nationals of Nigeria, Zimbabwe, Pakistan and India, H. Muhammad Prasetyo told reporters at the state palace. He did not say which day on the weekend.

Indonesia - which has some of the toughest anti-drugs laws in the world - executed 14 drug convicts, mostly foreigners, in two batches last year.

Activists intensified pressure on Indonesia's leader this week, urging him not to proceed with the third round of executions since he took office in October 2014.

The United Nations on Wednesday called on Indonesia to immediately reinstate a moratorium on the death penalty and not proceed with the executions.

"The executions will reportedly be carried out later this week at a high security prison on Nusa Kambangan island in central Java," the statement said, adding that the UN was deeply concerned about a lack of transparency throughout the process and by compliance with fair trial guarantees, including the right to appeal.
