Turkish Prime Minister Recep Tayyip Erdogan charged yesterday that Western powers were "keeping mum" over mounting bloodshed in the Middle East, warning that they would "pay the bill" by facing more terrorist attacks, Anatolia news agency reported. "Bombs are exploding, innocent people are being killed, infrastructures are being destroyed... The powerful continue to crush the weak, but unfortunately those who hold the power in the world are keeping mum," Erdogan said in the northeastern city of Artvin."Those who back global peace (only) with words will sooner or later pay the bill by facing global terrorism... This is what is provoking terrorism," he was quoted as saying. Erdogan complained that violence in the Middle East was also damaging the United States' efforts to enhance democracy and human rights in the region, hinting that Ankara might reconsider its role in such initiatives. He urged the Group of Eight leaders to push for a cease-fire in the crisis and harshly criticized Israeli military offensives. "I appeal to the G-8 countries to take a joint decision ... (for) the UN Security Council to ask for a cease-fire... They have to work this out," Anatolia quoted him as saying.
