HAIFA, ISRAEL - Israeli officials say two small fires that broke out in the same general area where an inferno is raging appear to have been deliberately set but it's unclear if they're connected to the larger forest fire.

Police spokesman Micky Rosenfeld says a bicycle and an unspecified head covering found near the scene of one of the fires suggested arson was to blame. Another police official, Roni Atia, says two suspects have been detained in connection with one of the small fires, which were quickly contained.

Rosenfeld says it's still too early to determine the cause of the big blaze, which remained out of control Friday afternoon.
