United Nations Secretary General Ban Ki Moon has welcomed a proposal by Greece to carry out, along with the UN, the sea transport of aid shipments to the Gaza Strip, Athens said Monday, according to dpa. Greek Foreign Minister Stavros Lambrinidis said he had talked late the night before by telephone with Ban to discuss the idea. The UN chief had welcomed it and said this could help lead to a reducing of tensions in the Middle East region. Greek President Giorgos Papandreou made the proposal on Sunday in a telephone call with Palestinian President Mahmoud Abbas, who for his part pledged his support.
