Three college friends of the Boston bombings suspect have appeared in court, accused of obstructing the police investigation into the attacks.

Azamat Tazhayakov and Dias Kadyrbayev - both from Kazakhstan - threw away Dzhokhar Tsarnaev's laptop and backpack, police say.

Robel Phillipos is accused of lying to investigators. None of the three are implicated in plotting the attacks.

Three people died and 264 were wounded in the 15 April marathon blasts.
