Germany reclassifies the United States, Israel, Turkey, Kenya, Montenegro and Vietnam as "high risk" COVID-19 areas, triggering mandatory 10-day quarantines for unvaccinated travellers unless they can show a negative test after five days. The changes will be in effect from August 17 for Turkey and from August 15 for the rest of the countries.
The United Kingdom adds Turkey, the Maldives and Nepal to its "red list" of countries, where travellers will be required to quarantine in a hotel for 10 days upon their return to the UK at their own expense. Twelve countries are also added to the government's "green list", including Portugal and Israel. This new "traffic light system" will take effect on May 17, when international travel is no longer illegal.
A group of more than 30 journalists from such countries as Turkey, Spain, Germany, Lebanon, Egypt, the United Kingdom and the United States announces it is to take legal action against Israel for equipment lost and money stolen due to the Gaza flotilla raid.
Turkey buries its citizens killed in the raid. Israel states there is "no need" for an international inquiry because it expects its own inquiry to meet the "highest international standards." President of Turkey Abdullah Gül states relations between the two countries would "never be the same".
Israeli Prime Minister Benjamin Netanyahu will send deputy prime-minister to a summit on nuclear weapons in the United States over concerns that Egypt and Turkey might shift the focus away from preventing militants from obtaining nuclear weapons by insisting that Israel sign the Nuclear Non-Proliferation Treaty (NPT).
