BERLIN (Reuters) - Germany's Bundestag lower house of parliament on Thursday overwhelmingly approved a petition on support for Ukraine backing the delivery of weapons including heavy arms to the country to help it fend off Russian attacks.

       "Alongside the broad economic isolation and decoupling of Russia from international markets, the most important and effective means to stop the Russian invasion is to intensify and speed up the delivery of effective weapons and complex systems including heavy arms," the petition read.

       The petition was backed by both the three parties in the ruling coalition as well as the opposition conservatives, passing with 586 votes in favor, 100 against and seven abstentions, according to Bundestag Vice President Wolfgang Kubicki.
