NAIROBI, June 10 (Reuters) - At least 15 people were killed when a wall at a brick factory collapsed in the Kenyan capital Nairobi after heavy rain, witnesses said on Sunday.

The wall fell onto people living in tin-roof huts next to the factory, a Reuters photographer saw. Several people were injured.

Witnesses said the wall collapsed late on Friday.

Nairobi has seen several deadly collapses in the past year, with experts blaming poor construction, unlicensed builders and ineffective regulation.
