MILITARY DEAL AT RISK

The Brazilian government said in a statement it was shocked by the news, which marked the second execution of a Brazilian in Indonesia in three months despite President Dilma Rousseff's personal humanitarian appeals.

Brazil's foreign ministry said it was evaluating ties with Indonesia before deciding what action to take. It recalled its former ambassador in Jakarata after the first execution and said Wednesday it had no plans to replace him.

"Given the lack of a satisfactory reply to our appeals, this has to be evaluated to decide what attitude we will adopt towards Indonesia from now on," Brazil's Deputy Foreign Minister Sergio Franca Danese told reporters.

Indonesia said earlier it was reviewing its procurement of a squadron of 16 Brazil-made Embraer EMB-314 Super Tucano aircraft and an order for multiple rocket launch systems after Brazil refused to allow Indonesia's new ambassador to take part in a credentials ceremony.

The United Nations described the executions as "extremely regrettable, extremely sad" and reiterated its appeal for Indonesia to reinstate its moratorium on the death penalty.

"Indonesia appeals for clemency when its own nationals face execution in other countries, so it is incomprehensible why it absolutely refuses to grant clemency for lesser crimes on its own territory," said Rupert Colville, U.N. human rights spokesman in Geneva.

The families of Australians Chan and Sukumaran released a statement early on Wednesday that said they were grateful for the support they had received.

"Today we lost Myuran and Andrew," the statement said.
