AlHijjah 22, 1432, Nov 18, 2011, SPA -- Croatian doctors have filed war crimes accusations against 19 former Yugoslav army commanders for the relentless shelling of a hospital in Vukovar during an 87-day siege of the eastern Croatian town in 1991, according to AP. The head of the hospital, Vesna Bosanac, said Friday that 500-700 grenades hit the facility during the bombardment by the Serb-led Yugoslav army. She says the complaint for the breach of the Geneva Conventions forbidding wartime attacks against civilian targets was filed with a local Croatian court. It will now be investigated by prosecutors. Thousands of people are expected to take part in a memorial march in Vukovar on Friday to mark the 20th anniversary of the siege that became the symbol of Croatia's fight for independence. -- SPA
