Ramadan, the holy month of Islam, began Saturday with Iraqis hoping for tranquility but fearful after recent attacks that have shaken the country. Al-Iraqia state TV interrupted regular programming Saturday afternoon to broadcast Prime Minister Nuri al-Maliki’s address to Iraqis on the occasion of the start of the holy month. The prime minister said that as he congratulates Iraqis, his “heart is full of sadness and sorrow.” Four Iraqi soldiers and a government worker were killed Saturday in attacks in Baghdad and Mosul, according to an official of the Interior Ministry.
