Emergency UN mission to Indonesia
A UN driver from the attacked convoy was questioned by police on Monday
The head of the United Nations' mission in East Timor, Ian Martin, is flying for urgent talks in the Indonesian capital, Jakarta, after a series of attacks by pro-Indonesian militias on unarmed UN officials.
He said he had no doubt the militias were under the control of the Indonesian army - which has always denied involvement.
Pattern of attacks
Sunday's attack was the third on the UN in a week by the pro-Jakarta paramilitaries. Last Tuesday the UN office in the town of Maliana was badly damaged and there have been numerous threats against UN personnel.
Two vehicles belonging to the UN mission, Unamet, were involved in the attack. A driver was shot and hospitalised and six people are reported missing.
BBC Jakarta Correspondent Jonathan Head says despite promises to protect the UN mission, some of the Indonesian government's statements have been less than reassuring.
Indonesia issued a statement saying it "strongly deplores and is seriously concerned" over the assault, which it said was committed by a group of East Timorese.
The statement did not identify the attackers as members of the Besi Merah Putih (Red and White Iron) militia, which controls the Liquisa district and is backed by the regular army.
Diplomates believe the Indonesian government does not want the embarrasment of seeing the whole UN mission collapse, but without a dramatic change in the security situation, that is exactly what will happen.
Annan envoy in Sydney
The UN envoy, Jamsheed Marker, said the body would make its concerns known "only too clearly" to Indonesia about what he described as unfortunate incidents. Mr Marker is also planning to return to Jakarta.
Mr Downer was more forthright. "The United Nations and the international community will not be bullied by a bunch of hoodlums and thugs from militias", he said on Monday.
