MANAMA — A bomb explosion killed a Bahraini citizen and wounded an expatriate man on Tuesday, the Interior Ministry said, the second fatal attack in the Gulf Arab state in as many days.

Political tensions have been running high in the kingdom since the opposition boycotted elections last month.

The ministry called Tuesday’s attack a “terrorist explosion” and said police were on the scene of the blast in a village southwest of the capital Manama. Bahrain’s largest Shi’a opposition group, Al Wefaq, condemned the attack.

On Monday, a Jordanian officer on a security exchange program in Bahrain was killed by a locally made remote-controlled bomb in the village of Damistan, also southwest of Manama, the Interior Ministry said in a statement.

Bahrain’s foreign minister described the killing of Corporal Ali Mohammed Ali as a terrorist attack using a bomb made by the Lebanese group Hezbollah.

The Interior Ministry’s website cited Major General Tariq Al Hassan, the kingdom’s chief of public security, as saying that several suspects had been arrested over Monday’s attack.

In November the opposition boycotted parliamentary elections, complaining that changes to voting districts would favor the Sunni Muslim minority represented by the ruling family.

Gulf leaders meeting in the Qatari capital Doha on Tuesday were expected to discuss security issues in a Middle East region badly shaken by sectarian bloodshed, though the energy-rich Sunni Gulf monarchies have been largely spared.
