Two violent clashes between groups of foreigners in central Athens over the weekend led to one man being killed and another being hospitalized in critical condition. In the first incident early on Sunday, three Pakistanis and four Albanians came to blows in the street in the central district of Aghios Panteleimonas after the latter group allegedly threatened the Pakistanis to hand over their money. In the scuffle that ensued, a 27-year-old Pakistani was stabbed and died a few hours later in the hospital. The second clash, early yesterday, occurred in a bar in Patissia, north of the center, between a group of Romanians and Albanians. A 23-year-old Romanian doorman was shot in the chest during the fight. The district of Aghios Panteleimonas was shaken again early yesterday when unknown assailants hurled three hand grenades at a local pizzeria, causing extensive damage but no injuries. The attack, which occurred while the shop was closed, is believed to have been carried out by extortionists. By late yesterday there had been no arrests for any of the three incidents.
