Harare - Zimbabwe will hold its general elections on July 30, the first since the army forced 94-year-old former president Robert Mugabe to resign last November.

President Emmerson Mnangagwa, who became president following the military take-over, has promised to deliver on free and fair elections to win over Zimbabwe's critics at home and abroad.

On July 11, Zimbabwe's main opposition party marched to the independent election agency for the second time in as many months, demanding reforms it said were vital for a credible vote this month.

As Zimbabweans face the looming election, the government of Zimbabwe has, with effect from July 1, hiked salaries for the security sector.

A data leakage scandal has hit Zimbabwe's election after the ruling party sent personalised, unsolicited campaign messages to potential voters' mobile phones on July 10.

The opposition says thousands of supporters reported receiving the messages. 

On June 23 a grenade blast at an election rally in the country's second largest city of Bulawayo killed two people and narrowly missed President Emmerson Mnangagwa. About 50 people were injured in the blast, which exploded as Mnangagwa left the podium after addressing supporters of the ruling ZANU-PF party.

Zimbabwe police have arrested two suspects. 

"I would like to applaud the level of cooperation and support that the joint investigation team has so far received, culminating in two suspects being accounted for," Police chief Godwin Matanga said while addressing police officers in Bulawayo this week. 

"We will never rest until all those behind this heinous act have been accounted for and have their day in court."

Previous elections under Mugabe were marred by violence, intimidation and fraud.
