UPDATE2: 40 people die in explosions in Pakistan tribal areas+
At least 40 have died in three separate attacks on election rallies in northwest Pakistan's turbulent Khyber Pakhtoonkhwa Province during the last 48 hours, police and administration officials said Tuesday.
The latest attack took place on an election convoy of a Pakistan Peoples Party candidate in the Lower Dir district of the province.
"The explosion was caused by an IED (improvised explosive device)," a witness said.
A brother of the candidate for the provincial assembly leading the convoy escaped, but six other people were killed.
Earlier Tuesday, 10 people were killed and 35 injured in an explosion at a rally of the religious Jamiat Ulema-e-Islam-Fazl (JUI-F) party in Khyber Pakhtoonkhwa, just a day after 24 people were killed at a similar gathering in restive northwestern Pakistan, police said.
Police said a suicide bomber blew himself up near the vehicle of a JUI-F candidate, Syed Janan, minutes after the public meeting in the Hangu area.
Janan, who was running for the provincial assembly, and his two body guards were among those injured.
Hangu, about 225 kilometers southwest of Peshawar, is a semitribal area and a stronghold of the Pakistani Taliban.
On Monday, a bomb exploded during a public meeting of two JUI-F candidates in the tribal agency Kurram bordering Afghanistan, killing 24 people.
Both explosions hit public meetings linked to the JUI-F, which once backed the government in Islamabad and in Khyber Pakhtoonkhwa.
JUI-F cut the links with the government ahead of Saturday's general elections.
