Narrative:
On approach to runway 24R at lax, in WX, on GS. At about 6000 ft received a TCASII alert showing an aircraft 1000 ft directly above us. TCASII showed that aircraft above was descending at rate down towards us. At about 600 ft we received a TCASII warning to increase rate of descent. Once clear of clouds, saw a B767 off left side on runway 25L approach. We initiated increase in vertical speed at TCASII warning.
