The Indonesian government has asked Timor Leste President Jose Ramos Horta to provide evidence to support his allegation that Timor Leste rebel commander Alfredo Reinado had received support from "elements in Indonesia", according to Antara. "If Timor Leste can provide evidence, we will be ready to take follow up action on the allegation," Indonesian Foreign Affairs Minister Hassan Wirajuda said here on Thursday. "We want the allegation to be supported by substance," Wirajuda said in response to ANTARA`s questions. For Indonesia, it would not be difficult to investigate the matter as long as Timor Leste provided supporting materials, the minister said. "We have an open mind. If there is information, for instance on phone calls or money transfers, give it to us. With such information it`s easy to trace the people involved," he said. If the Timor Leste government could provide the information, not only the foreign affairs ministry would investigate the matter, but also other Indonesian government institutions, including the immigration office, Wirayuda said. "We hope the existing good communications with Timor Leste can be maintained. We have demonstrated our transparency and we have a very good understanding of the conditions in Timor Leste," the minister said. "We are very supportive of the efforts to maintain security there. For instance, whenever there is a request (from Timor Leste) to close the border, we do it. And when the border closure affects the trans-border flow of goods and services so that the border needs to be reopened, we oblige," he said. Ramos Horta was quoted by the Associated Press as saying in Dili recently there was a possibility rebel army officer Alfredo Reinado, who had tried to assassinate him in an armed attack on his residence but was himself killed in an ensuing shootout, had "a lot of contacts ... with elements in Indonesia".
