Storms in Switzerland and northern Italy caused extensive flooding and landslides, leaving at least four people dead, authorities said Sunday.

The bodies of three people were recovered following a landslide in the Fontana area of the Maggia valley in the Italian-speaking Ticino canton (state) on the southern side of the Alps. Storms and heavy rain pounded southern and western Switzerland on Saturday and overnight.

A portion of a canopy at a departure terminal at New Delhi's Indira Gandhi International Airport collapsed Friday as monsoon rains lashed the Indian capital, killing one person and injuring six others, officials said.

All flight departures from Terminal 1 were temporarily suspended as rescuers cleared the debris to rescue anyone trapped there, the airport authority said.

Severe weather over days has caused havoc and destruction across the U.S. That includes torrential rains and flooding in the Upper Midwest and powerful storms in the Northeast that left a least two people dead from falling trees.

The deadly storms that raked parts of the Northeast late Wednesday into early Thursday spun off tornadoes and initially left some 250,000 customers in the region without power.
