Hungry and exhausted Armenian families jammed roads on Tuesday to flee homes in the defeated breakaway enclave of Nagorno-Karabakh, a departure blighted by an explosion at a fuel depot that killed dozens and injured more than 100. The crisis prompted the US Agency for International Development (USAID) to announce that Washington would provide $11.5 million in humanitarian assistance, Reuters said. "We urge continued humanitarian access to Nagorno-Karabakh for all those in need," White House National Security Council spokesperson Adrienne Watson said.
