By Andrew MacAskill, Federico Maccioni and Pesha Magid LONDON/DUBAI (Reuters) -Israel's strikes on Iran's nuclear installations so far pose only limited risks of contamination, experts say. But they warn that any attack on the country's nuclear power station at Bushehr could cause a nuclear disaster.

Since the war began last week with Israeli attacks on Iranian nuclear sites, the Emirates has waived all visa overstay fees for Iranians stranded in the country. On Tuesday, the Emirati ruler, Sheikh Mohammed bin Zayed, called the Iranian president to express “solidarity with Iran and its people during these challenging times.”
