By Aleksandar Vasovic SLAVIANSK, Ukraine (Reuters) - At least three people were killed in a gunfight in the early hours of Sunday near a Ukrainian city controlled by pro-Russian separatists, shaking an already fragile international accord that was designed to avert a wider conflict. The incident triggered a war of words between Moscow and Ukraine's western-backed government with each questioning the other's compliance with the agreement, brokered last week in Geneva, to end a crisis that has made Russia's ties with the West more fraught than at any time since the Cold War. The separatists said armed men from Ukraine's Right Sector nationalist group had attacked them. Failure of the Geneva agreement could bring more bloodshed in eastern Ukraine, but may also prompt the United States to impose tougher sanctions on the Kremlin - with far-reaching consequences for many economies and importers of Russian energy.
The unmanned Dragon capsule from the private US firm SpaceX successfully berthed at the International Space Station Sunday on its third trip carrying supplies and equipment to the orbiting lab. NASA television broadcast live images of the crew inside the ISS as the capsule was installed on the Earth-facing port of the Harmony module, a US-built utility hub, at 1406 GMT. It said the capsule, which berthed with the help of a long robotic arm, took place 260 miles (418 kilometers) above Brazil. "Capture complete, congratulations to the entire team," said the Japanese station commander, Koichi Wakata, who was in charge of operating the mechanical arm along with American Rick Mastracchio.
Twitter blocked two accounts on Sunday that had been used to spread corruption allegations against Turkish Prime Minister Recep Tayyip Erdogan, his government and his inner circle. The move came after high-level meetings between the government and executives from the company last week, and after the Turkish government provoked a storm in March by trying to ban the network entirely. Between them, @Haramzadeler333 (which translates as "Sons of Thieves") and @Bascalan (which means "Prime Thief", a play on the Turkish for prime minister) had close to one million followers on Twitter. Twitter's global policy team said it withholds content only "after due process", such as after having received a court order, and in a tweet said it would not do so "at the mere request of a gov't official".
