This week in pictures: Beirut blast; Hiroshima 75th anniversary; and Belarus election rally

This week's most striking images came from Beirut where a huge explosion in the port area of the Lebanese capital left at least 137 dead and more than 5,000 injured.

Also proving photogenic over the last seven days were events to mark 75 years since the Hiroshima and Nagasaki atomic bomb attacks; a stunt to support Poland's LGBT community at the swearing-in of re-elected president Andrzej Duda; and an opposition rally in Belarus ahead of presidential elections on Sunday.
