In Cambodia, more than 100 civilians are killed and 280 wounded as communist Khmer Rouge artillery and rockets strike Phnom Penh and outlying areas in the heaviest attack since the beginning of the war in 1970. Following the shelling, a communist force of 500 troops attacked and entered Ta Khmau, six miles southeast of Pnom Penh, killing at least 25 civilians.
