Diplomat axed in passport row
Australia moved to expel an Israeli diplomat today after investigators concluded Israel was responsible for forging four Australian passports that were used in the killing of a Hamas operative in Dubai.
Foreign Minister Stephen Smith said the operation to kill Mahmoud al-Mabhouh in a luxury Dubai hotel room in January was not the first time Israel had forged Australian travel documents.
"These are not the actions of a friend," he said.
Dubai authorities accused Israel's Mossad intelligence agency of carrying out the killing, and identified at least 26 suspects from an alleged hit squad.
Clear skies at crisis volcano
The volcano that sparked the ash crisis causing chaos across Europe's skies is quiet but it is "too early to say this is over", an Icelandic expert said.
The eruption of Eyjafjallajokull on April 14 was the first in nearly 200 years and led to an estimated 10 million travellers being grounded around the world.
The Icelandic Civil Protection Agency said steam was coming out of the volcano, but no ash.
Mammoth gas warmed Earth
Gassy mammoths helped to fill the atmosphere with methane and keep the Earth warm more than 13,000 years ago, scientists believe.
Together with other large plant-eating mammals that are now extinct, they released around 9.6 million tonnes of the gas each year, said experts at the University of New Mexico in the USA who analysed gases trapped in ice cores.
When the "megafauna" disappeared, there was a dramatic fall in atmospheric methane which may have altered the climate.
