A court document says a doctor prescribed oxycodone for Prince under the name of the musician's friend to protect his privacy.

On the western side of Mosul, much of the fighting against Islamic State militants takes place between houses so close that they almost touch. Snipers fire from roofs and through holes blasted into outer walls.

Seen through these holes, this part of Iraq's second-largest city is a landscape of half-collapsed buildings, burned-out cars and rubbish-strewn streets. Helicopters hover and barricades of sandbags block the streets.

Syrian regime forces and their allies advanced Monday in the central province of Hama under the cover of intense airstrikes, approaching the outskirts of a rebel-held town a day after capturing a strategic town from opposition fighters and militants, Syria's state media and opposition activists said.

The push toward the town of Tibet al-Imam came a day after troops and pro-government militiamen captured the town of Soran, a month after Soran was lost in a rebel offensive. The government appears to be aiming to secure areas north of the city of Hama, the country's fourth largest.

Egyptian security officials say three people have been injured in clashes between militants and local tribes in the Sinai peninsula.

The officials told The Associated Press Monday that militants from the Islamic State group launched RPG attacks Sunday in response to the kidnapping of three of its members by local tribes.

More than 3,000 Syrians are expected to be evacuated Sunday from four areas as part of a population transfer that was briefly stalled the day before by a deadly blast that killed scores of people, most of them residents of the besieged Shiite towns Foua and Kfarya.

An Iraqi military statement says the Syrian air force has carried out a series of airstrikes against Islamic State group militants inside Syria, with one killing the group's leader in Raqqa, the IS de facto capital

Saturday's statement doesn't say when the airstrikes happened, but described the targets as "the biggest positions for senior terrorists."

Campaigning for Turkey's crucial referendum on whether to expand presidential powers has entered its final stretch, with President Recep Tayyip Erdogan addressing flag-waving supporters in an Istanbul neighborhood to drum up support for his "yes" campaign.

Erdogan has long championed the idea of changing Turkey's system of government from parliamentary to presidential. He is calling on his countrymen to vote on Sunday to approve constitutional changes that would abolish the office of the prime minister, handing all executive power to the president. The change, he says, will bring much-needed stability to Turkey.

Backed by Russian air power and allied militiamen on the ground, Syrian troops have recaptured entire cities from rebels and Islamic State group extremists in the past year, including the key cities of Aleppo, Homs and Palmyra.

Yet for the past three years, President Bashar Assad's forces have been unable to free opposition-held neighborhoods of the capital Damascus, where rebel fighters have built a labyrinth of secret underground tunnels, beyond the reach of airstrikes and connected to opposition-held suburbs farther out.

A train with about 1,200 passengers became stuck in a tunnel between New York and New Jersey for nearly three hours on Friday, and the chaotic scene escalated to pandemonium when Amtrak police used a stun gun to subdue a disruptive man in a station, sparking a stampede.

It was the latest in a series of recent rail problems plaguing the metropolitan area.

Thousands of Syrians were bused out of their towns on Friday in the first stage of a widely criticized population transfer that reflects the relentless segregation of Syrian society along political and sectarian lines.

The coordinated evacuations delivered war-weary fighters and residents from two years of siege and hunger, but moved the country closer to a division of its national population by loyalty and sect.
