Bahrain's main opposition party, al-Wefaq National Islamic Society, say a Bahraini woman has succumbed to gunshot wounds she had earlier sustained to her head.
Bahiya al-Aradi martyred on Tuesday and her funeral held at at 3:00 pm.
Wefaq said the exact circumstances of how she was shot were not clear. She had apparently been driving her car in the west of the capital Manama on Wednesday, when security forces launched a crackdown against anti-regime protesters.
The dispatch of troops from Saudi Arabia and other Persian Gulf allies of Bahrain has highlighted concerns about possible spillover of the uprising in the country, where month-old protest rallies seek to end the Western-backed government's monopoly on power.
Saudi and other Arab rulers fear that any concession by Bahrain's rulers could embolden more protests against their own despotic rules.
Recently, mass protests in Jordan, Kuwait, Oman, Saudi Arabia and Yemen have also demanded government reforms.
Foreign military interventions in Bahrain have served as a cause of concern for UN Secretary General Ban Ki-moon, who has called for a meaningful and broad-based national dialogue.
