European lawmakers aim to get firsthand knowledge of the civilian impact of the war in Libya by talking with refugees in Tunisia, a visiting official said.A delegation of six lawmakers from the European Parliament is examining the situation facing Libyan refugees who have fled to Tunisia.Simon Busuttil, the lead delegate from Malta, said European leaders have a responsibility to address the humanitarian challenges facing Libyan refugees.Renewed violence in Tunisia could complicate the refugee situation. Six policemen were injured in clashes last weekend and a 14-year-old boy was killed when riot police tried to quell the violence in Sidi Bouzid, the site of the first clashes in the Tunisia revolution that brought down the government of Zine el-Abidine Ben Ali after more than 23 years in power.The government said recently it was delaying national elections by three months to October."Transitions are not easy, especially seismic transitions such as the one Tunisia is going through," said U.N. High Commissioner for Human Rights Navi Pillay in a statement during her visit last week.
