Iraqi militants seize second city of Mosul

Iraq's prime minister has asked parliament to declare a state of emergency after Islamist militants effectively took control of Mosul.
Nouri Maliki acknowledged "vital areas" of the country's second largest city had been seized.
Overnight, hundreds of armed men seized local government's offices and police stations before taking control of the airport and the army's headquarters.
About 150,000 people are believed to have fled the city.
Sources have told BBC Arabic that they are heading to three towns in the nearby region of Kurdistan where authorities have set up temporary camps for them.
Kurdistan Prime Minister Nechirvan Barzani issued a statement appealing for the UN refugee agency to help those fleeing Mosul.
Elsewhere, a double bomb attack in the central town of Baquba killed at least 20 people, police and medics said. The blasts, targeting a funeral procession, also wounded 28 people.
Security sources also told the BBC on Tuesday that fierce fighting had erupted between Iraqi forces and ISIS fighters in a town called Rashad near Kirkuk, south-east of Mosul.
The BBC's Jim Muir in Beirut says ISIS has been informally controlling much of Nineveh province for months, imposing tolls on the movement of goods and demanding protection money from local officials.
After five days of fighting, they took control of key installations in Mosul, which has a population of about 1.8 million.
