US Interceptor Missile Successfully Intercepts Test ICBM, Says Pentagon (go.com) 136
An anonymous reader writes: The Pentagon has confirmed that the U.S. interceptor missile it launched has successfully intercepted the test ICBM fired from the Marshall Islands. From an ABC News report detailing the intercept test: "The ground-based interceptor launched from Vandenberg Air Force Base in California shortly after 3:30 p.m. EST Tuesday. The U.S. will launch an ICBM-class target from the Ronald Reagan Ballistic Missile Defense Test Site on Kwajalein Atoll in the Marshall Islands, 4,200 miles away. If successful, the kill vehicle, or intercept, will collide with the ICBM test target midcourse over the Pacific Ocean later today. The ground-based interceptor system is mainly designed to counter a North Korean missile threat, but a U.S. official said Tuesday's test has been planned for years and is coincidental to North Korea's increased missile testing this year. This will be the 18th test of the ground-based interceptor. The last one, in June 2014, was the first success since 2008. The system is nine for 17 since 1999 with other types of target missiles. An ICBM target has never been tested before."

This article doesn't give anything close to enough information to know how accurate this system is in 2017. This is the only test to shoot down an ICBM, and we haven't tested against shorter ranged missiles since 2008 (according to TFA). They were certainly not very reliable from 1999-2008, but they may be far more accurate now. Obviously only one test is not enough data points to determine an overall success rate.
And just as NK could launch multiple nukes, the US could launch multiple interceptor missiles.

The idea is to take down the missile thousands of miles from the US border, so the EMP will not affect its target.

No, you win quite a lot. There are examples of the non-nuclear explosives in a nuclear weapon detonating in an uncontrolled manner, and the nuclear fallout is many orders of magnitude less than a proper nuclear detonation.
