Lead screening conducted on west Maui residents after last summer's devastating wildfires showed no widespread exposure to the toxic metal, Hawaii health officials said.

Blood samples were taken from 557 people after the deadliest U.S. wildfire in more than a century ripped through the town of Lahaina, killing 101 people.

A Brazilian horse nicknamed Caramelo by social media users garnered national attention after a television news helicopter filmed him stranded on a rooftop in southern Brazil, where massive floods have killed more than 100 people.

About 24 hours after he was first spotted and with people clamoring for his rescue, a team in Brazil's Rio Grande do Sul state on Thursday successfully removed Caramelo, providing a dose of hope to a beleaguered region.

Hundreds of volunteers have set up a makeshift dog shelter in an abandoned, roofless warehouse in the Brazilian city of Canoas, one of the hardest hit by floods since last week. They treat and feed sick, hungry or injured dogs, hoping to reunite them with their owners.

Their work was at full speed Friday morning as heavy rains are expected again in the region for the weekend.

In sweltering Brazil, flooding killed dozens of people and paralyzed a city of about 4 million people. Voters and politicians in India, amid national elections, are fainting in heat that hit as high as 115 degrees (46.3 degrees Celsius).

A brutal Asian heat wave has closed schools in the Philippines, killed people in Thailand and set records there and in Indonesia, Malaysia, the Maldives and Myanmar. Record temperatures — especially at night when it just won't cool down — have hit many parts of Africa. Flooding devastated Houston, and the United States as a whole just had its second highest number of tornadoes for the month of April.

As major floods engulfed entire cities in the northern part of the Brazil's Rio Grande do Sul state last week, meteorologist Estael Sias knew the water would drain into capital Porto Alegre's metropolitan region and that she would need to find a safe place.

So she, her husband, three children, and two dogs left everything behind. Less than 24 hours later, water started filling her neighborhood in Canoas, now one of the state's most affected cities.

Forecasters warned a wave of dangerous storms in the U.S. could march through parts of the South early Thursday, after storms a day earlier spawned damaging tornadoes and massive hail, leaving two dead in Tennessee and one dead in North Carolina.

The storms continue an outbreak of torrential rain and tornadoes that has cut across the country this week, from the Plains to the Midwest and now the southeastern U.S. At least four people have died in storms since Monday.

The opening ceremony of the third edition of the Middle East Clean Energy Exhibition and Conference took place on Wednesday afternoon, May 8th. The event was attended by Minister of Energy and Water Walid Fayad. The exhibition and conference, specialized in clean and renewable energy, showcased cutting-edge technologies, along with a range of related solutions and services. Exhibitors presented their commercial products, including inverters, panels, batteries, solar heaters, and project financing. The event is scheduled to run until May 10th, 2024, at Hotel Phoenicia in the heart of Beirut.

The ceremony began with the Lebanese national anthem, followed by a speech by Beirut Expo's founder, Farhat Farhat, emphasizing the importance of holding such initiatives despite internal challenges and the war in southern Lebanon.

A tornado destroyed homes, forced the evacuation of a nursing home and toppled trees and power lines when it roared through a small Oklahoma town, one of several twisters that erupted in the central United States amid a series of powerful storms that stretched into Tuesday. At least one death was reported.

The tornado ripped through the 1,000-person town of Barnsdall, about a 40-minute drive north of Tulsa, on Monday night. It was the second tornado to hit the town in five weeks — a twister on April 1 with maximum wind speeds of 90 to 100 mph (145 to 161 kph) damaged homes and blew down trees and power poles in Barnsdall.

Jordan on Monday stationed two helicopters in Cyprus to help the Mediterranean island nation combat potential forest fires until it can lease firefighting aircraft of its own for the summer fire season.

Cypriot Environment Minister Maria Panayiotou said the Cypriot government considers firefighting and prevention a national security matter and is also moving to purchase 10 aircraft for that reason.

Spain's Catalonia region will ease restrictions on water use for a wide area including Barcelona after recent rainfall palliated a prolonged drought, regional authorities said Tuesday.

Catalonia declared a drought emergency in February when its reservoirs fell under 16% capacity after nearly three years of below-average rainfall. But steady rain in recent weeks has boosted reserves to nearly 25%. Spain's reservoirs overall are at 66% full.
