Alarm over recent deaths at Lesbos camp

Aid groups have raised alarm over the deaths of three migrants on Greece's Lesbos island inside a week.

They said that poor conditions at an overcrowded 
camp in Moria presented a "serious risk" to at least 
3,000 migrants living there.

A man in his 20s said to be a Pakistani was found dead in 
his tent on Monday.

A 22-year-old Egyptian man and a 46-year-old Syrian man 
who shared a tent died last week. Reports suggest they inhaled toxic fumes from heaters.

Greek police are now investigating the deaths.

Local media have cited carbon monoxide poisoning 
as a possible cause of deaths, as the cold winter weather 
has forced many migrants to use heaters and wood-
burning stoves to keep warm.

"Something has got to give," International Rescue 
Committee Greece director Panos Navrozidis was 
quoted as saying by Reuters. "We cannot tolerate this 
wanton loss of life."

The Doctors of the World charity said poor conditions 
at the camp posed "serious risk" to migrants.

More than 60,000 migrants and refugees - many of them
 from conflict-ravaged countries like Syria, Iraq and Afghanistan - currently live in camps around Greece.

Aid groups say many of the camps are overcrowded, 
with Human Rights Watch describing the conditions in 
some of them as "deplorable and volatile".
