Oil Weapon Update from [1] AP:

SAN`A, Yemen - Suicide bombers tried to strike two oil facilities in Yemen with explosives-packed cars, but authorities foiled the attacks and four bombers and a security guard were killed, the government said Friday.

The attempts came ahead of this week's presidential elections, in which President Ali Abdullah Saleh faces a serious challenge for the first time since he became head of state in 1978.

They also came days after al-Qaida's No. 2, Ayman al-Zawahri, issued a videotaped threat of attacks on the Persian Gulf and on facilities he blamed for stealing Muslim oil.
