SCOTT SIMON, HOST:

American flags are flying at half-staff today over the White House, and elsewhere in the country. The shootings in Aurora have silenced politics as usual - at least, for the moment. The Romney and Obama campaigns have both pulled their TV ads from the air in Colorado, a state that had three top political advertising markets in the country this week. NPR's Ari Shapiro reports on a somber day on the campaign trail.

Opposition activists in Syria report that there's been another day of heavy shelling in a number of cities, as rebel fighters continue their guerrilla war to topple President Bashar Assad. Host Scott Simon talks with NPR's Peter Kenyon in Beirut, which has seen a huge increase in refugees in recent days.

The battle for Syria appears to have reached a decisive stage. Tanks are on the streets of Damascus as civilians flee the city, and rebels have seized outposts on the borders with Turkey and Iraq.

The opposition has shown a surprising military capability over the past few days. As fighting intensifies in the Syrian capital, there's an urgent push under way to organize the rebel force.

At the end of July, thousands of visitors will descend on one of the great literary landscapes of history for the London Olympics. And if they're lucky, they may find themselves getting a ride from a man who drives for a living, but lives to read. London cabbie Will Grozier occasionally joins Weekend Edition to discuss what he's been reading. Lately, he's been thinking about books for the London Olympics visitor — reads that put both the games and the host city in context. He shares his recommendations with NPR's Scott Simon.
