Germany has pledged 250,000 million euros to assist Afghan refugees in Pakistan at a time when the UN refugee agency is facing major budgetary constraints. "We are grateful to the German government for their generous donation," Guenet Guebre-Christos, the UN High Commissioner for Refugees (UNHCR) representative in Pakistan, said on Monday. "Even though record numbers of Afghans have been repatriated in recent years, there are still about 2.6 million left in Pakistan, most of whom need basic services such as health and sanitation," he added.
