By Guillermo Martinez and Ana Cantero VILLARDEVÓS (Reuters) -Scorching heat hampered efforts to contain 20 major wildfires across Spain on Sunday, prompting the government to deploy an additional 500 troops from the military emergency unit to support firefighting operations.

Specially trained firefighting units from Bonn, Dusseldorf and three other cities set off from Bonn at midday on Sunday to help Spain combat its severe wildfires, according to the Bonn Fire Department.
