Concerns over oil supply flared up once again after Saudi Arabia's stock market plunged, posting its largest decline in over two years on a mixture of reports about the arrest of a cleric and tanks heading towards Bahrain.
Authorities retained a Shi'ite cleric who called for a constitutional monarchy and an end to corruption and discrimination, Reuters reported quoting human rights activists.
A report in an Egyptian newspaper quoted eyewitnesses as saying that tanks were heading from Saudi Arabia to Bahrain.
"There are no Saudi Arabian tanks in Bahrain. Tanks identified on Monday evening were Bahraini tanks returning from Kuwait National Day celebrations, where military from several Allied countries participated in an event commemorating Kuwait’s liberation in 1991," a Bahrain government spokesman said in an email.
The jittery oil market is likely to continue to make headlines on Wednesday.
