Street demonstrations, the resignation of cabinet ministers and the arrest of his former vice president are pushing Guatemalan president Otto Perez Molina into a corner.

Protesters demanding Perez Molina's resignation blocked roads on the outskirts of Guatemala City on Tuesday, and a judge is expected to issue a ruling on allegations that former Vice President Roxana Baldetti accepted $3.7 million in bribes as part of a scandal that forced her from office.

Since Friday, five of Perez Molina's 13 cabinet secretaries have resigned, mainly because of the scandal.

Tensions are mounting ahead of the Sept. 6 elections, which are to elect Perez Molina's successor.

Some protesters are demanding the elections be postponed until the corruption scandal is resolved and Perez Molina resigns.
