United Nations Secretary-General António Guterres has expressed his profound concerns about escalating violence and “bellicose rhetoric” between Israel and Hezbollah along the Blue Line, the demarcation between Israeli and Lebanese armed forces. He warned Friday that the risk of a wider conflict in the Middle East is real - and must be avoided. The warning comes as Lebanon is already facing a severe humanitarian crisis due to socio-economic shocks, ongoing political instability and spillover from the Syrian crisis.
