The Canadian and Australian embassies in Jordan shut their doors to the public today because of an undisclosed security threat a day after Britain closed its embassy in Amman for the same reason, diplomats said.
"The two embassies closed until further notice due to the security situation. It's possibly related to the same security threat received by the British embassy," one Western diplomat who requested anonymity told Reuters.
Britain closed its embassy in Jordan yesterday because of fears of attacks on Westerners.
Jordanian authorities said the closure was unnecessary.
A spokesman at the British Foreign Office said its advice to British travellers to Jordan remained unchanged, but there was sufficient reason to close the mission temporarily.
The move comes two months after triple suicide bomb attacks on luxury hotels in Amman killed more than 50 people.
Al Qaeda in Iraq, led by Jordanian Abu Musab al-Zarqawi, claimed responsibility.
Last August, militants linked to Zarqawi were accused by Jordan of being behind a failed rocket attack on US warships in the Red Sea port of Aqaba.
Australia and Britain became targets over their support for the US-led invasion of Iraq in 2003.
Canada did not take part in the war but supports the US-backed Iraqi administration.
Jordanian officials said security authorities who assessed an undisclosed threat received by the British embassy had concluded the closure was unnecessary.
Police had tightened security around Western missions and hotels since the triple bombings that shattered Jordan's sense of being an island of stability in a troubled region.
