Six months after do**rs pledged billions of dollars (euros) for devastated Gaza, most of the money remains blocked, and reconstruction efforts are painfully slow, a coalition of aid groups said Monday. The report also condemned the international community for failing to help open the blockaded Palestinian territories up to each other, to broker a lasting ceasefire with Israel and to hold the two sides accountable. "If we do **t change course **w to address these core issues the situation in Gaza will only continue to worsen," Association of International Development Agencies (AIDA) said. "Without eco**mic, social and political stability, a return to conflict -- and the cycles of damage and do**r-funded reconstruction that accompany it -- is inevitable," the coalition added.
